It cooks the food by heating the moisture inside the food, i.e. Medium-length (C-band) microwaves penetrate through clouds, dust, smoke, snow, and rain to reveal the Earth's surface. #Mining Works, tunneling, breaking and boring works of rocks, concrete etc. In this post we will discuss two important concepts of optical fibers, these are- Acceptance Angle and Numerical Aperture (NA). #Drying grains, pharmaceuticals, textile industries, leather industries etc. Microwaves find applications in industries in the following areas-#Food Processing industries #Microwave oven (2.45 gigahertz, 600 watt) They are also used for supervisory control and data acquisition (SCADA) for remote machinery, switches, valves and signals. As an Amazon Associate I earn from qualifying purchases. Global Navigation Satellite System (GNSS) including the American Global Positioning System (GPS) and the Russian GLONASS broadcast navigational signals in various bands between about 1.2 GHz and 1.6 GHz. Many laboratory tests have been conducted to investigate microwave-assisted concrete curing, recycling, drilling and non-destructive monitoring. RADAR is used to illuminate an object by using a transmitter and receiver to detect its position and velocity. Like light waves, microwaves travel essentially in straight lines. A Gunn diode oscillator and waveguide are used as a motion detector for automatic door openers (although these are being replaced by ultrasonic devices). The longest frequencies are used in telescopes, while the shortest frequencies are used in GPS and cellular phones. Wireless Internet Access services can be found in many countries in the 3.5 – 4.0 GHz range.

Microwaves are a form of electromagnetic radiation with wavelengths between 10^-3 and 10^1. 2003 Jul 30;51(16):4764-8. Although microwaves were first produced and studied in 1886 by Hertz, their practical application had to await the invention of suitable generators, such as the klystron and magnetron. Such application of high-frequency electromagnetic (EM) radiation for the dielectric heating of materials is also one of the most widely adopted industrial uses for RF/microwave components and systems. So all the frequencies that fall between 1 gigahertz and 1000 gigahertz are microwaves. Many semiconductor processing techniques use microwaves to generate plasma for such purpose as reactive ion etching and plasma-enhanced chemical vapor deposition (PECVD). They can cause water and fat molecules to vibrate so they are used for cooking in microwave ovens. Instead of surgically removing the problematic organ, doctors can use microwaves to heat op the enlarging tissue of the prostate and in turn decreasing the size of the enlarged prostate. The IEEE 8.2.16 specification was designed to operate between 2 to 11 GHz. iBurst) are designed to operate between 1.6 and 2.3GHz to give mobility and in-building penetration characteristics similar to mobile phones but with vastly greater spectral efficiency. Microwave technology has wide range of application areas. it cooks from the inside to the outside. Another important application of microwaves is radar. Less-than-lethal weaponry exists that uses millimeter waves to heat a thing layer of human skin to an intolerable temperature so as to make the targeted person move away. Microwaves are used in various fields of our life. The major advantages of microwave heating are its short startup, precise control, and volumetric heating [].In industry, microwave heating is used for drying [2-5], oil extraction from tar sands, cross-linking of polymers, metal casting [], medical applications [], pest control [], enhancing seed germination [], and solvent free chemistry []. #Microwaves Properties and Advantages (Benefits), Pulse Code Modulation (PCM) Vs Differential Pulse Code Modulation (DPCM), LATEST SCIENTIFIC RESEARCHES (Includes Videos), SECRETS OF THE UNIVERSE (With Awesome Videos), EVERYDAY SCIENCE EXPLAINED (With Interesting Videos), TECHNOLOGY AND TROUBLESHOOTING (Includes Video Tutorials), Engineering Topics (With Video Lectures in HD), MODULATION TECHNIQUES (Analog and Digital), PULSE MODULATION Techniques (PAM, PWM, PPM, PCM), COMMUNICATION SYSTEMS (ANALOG AND DIGITAL), RANDOM VARIABLES and PROBABILITY DISTRIBUTION, Free Google Games to Play Now- elgoog Games- (Atari Breakout, Google Snake Game, T Rex Dash, Pacman), Low Level and High Level Modulation Block Diagram (AM Transmitter Block Diagram), Conventional AM Vs DSB-SC Vs SSB-SC Vs VSB - Comparison of AM Techniques - Types of Amplitude Modulation, Meridional and Skew Rays (Optical Fiber Communication), Thevenin Theorem - Thevenin Equivalent Circuit - Applications and Limitations of Thevenin Theorem, Digital Modulation Techniques (ASK, FSK, PSK, BPSK) - Amplitude, Frequency and Phase Shift Keying, FREQUENCY SPECTRUM OF AMPLITUDE MODULATION (WAVEFORMS AND EQUATIONS DERIVATION), PULSE MODULATION TECHNIQUES (PAM, PWM, PPM, PCM), STEP INDEX OPTICAL FIBER (MULTIMODE AND SINGLE MODE STEP INDEX FIBERS), Acceptance Angle and Numerical Aperture (NA) (Optical Fiber Communication).

There is a need to develop special transistors to tolerate the microwave frequencies. #Plastics industries, chemical industries, rubber industries, forest product based industries. Radio Detecting and ranging (RADAR) uses microwave radiation to detect the range, speed, and other characteristics of remote objects. Microwave irradiation is an electromagnetic spectrum with a frequency of wavelength band ranges from 300 MHz to 300 GHz (Wang and Wang, 2016b; Wei et al., 2020).The inherence of microwave irradiation is involved in penetration, reflection and absorption depending on the medium (Chou et al., 2013b) ().First, insulators are transparent, with a large penetration depth and a small … 2. Industrial Applications of Microwaves In industries we use microwaves because of its heating property, we know that microwaves have the capability to heat-up the things. Hence for microwave applications, silicon n-p-n transistors that can provide adequate powers at microwave frequencies have been developed. Starting in the early 1950’s frequency was used to send up to 5,400 telephone channels on each microwave radio channels combined into one antenna or the hop to the next site, up to 70 km away. Microwaves are primarily used in medical cases as an alternative to surgery.

They are with typically 5 watts at a frequency of 3GHz with a gain of 5dB. Abstract: Though this Special Issue is devoted to the history of microwaves, an appreciation of the history of the interaction of microwaves with biological systems would not be complete without also covering the role that lower frequencies have played in research directed toward the improvement of human health. #To calculate the distance of objects and to know the speed of moving objects etc. Due in large part to the overwhelming success of microwave ovens for home use, microwave processing is seen by the unwary as a panacea for all heating applications. The application areas are many can be categories in different ways. They are also used in radar which is used by ships, aircraft and weather forecasters. Microwave ovens become common kitchen appliances in Western countries in the late 1970s, following development of expensive cavity magnetrons. There are many advantages of Microwaves such as the following − Supports larger bandwidth and hence more information is transmitted. Microwave imaging, photo-acoustic imaging in biomedicine. Actually the wavelength of microwaves is 1 foot or less that is the wavelength is less than 30.5 cms which is nearly equals to 1 foot. This creates heat. They are used in radar, in communications links spanning moderate distances, and in other applications, such as microwave ovens microwave oven, device that uses microwaves to rapidly cook food. Licensed long-range (up to about 25 km). The applications of microwaves may be divided broadly in area as appended below. Recent applications for microwaves include ceramics and powder drying, diamond growth, and microwave pyrolysis. Cable TV and Internet access on coaxial cable as well as broadcast television use some of the lower microwave frequencies. For this reason, microwaves are used for point-to-point communications. Traditionally it has been used for telecommunication/communication purposes but it is also used for different kinds of sensing and imaging applications. Microwaves find applications in industries in the following areas-, #Microwave oven (2.45 gigahertz, 600 watt). The main use of microwaves in the baking industry today is the microwave finishing, when the low heat conductivity lead to considerable higher baking times in the conventional process. This post is about the generation of amplitude modulation. For more complicated applications, our microwave engineering team is available for more involved research and development.
