A microwave oven or simply microwave is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. [1] This induces polar molecules in the food to vibrate [2] and produce thermal energy in a process known as dielectric heating.
A telecommunications tower with a variety of dish antennas for microwave relay links on Frazier Peak, Ventura County, California. The apertures of the dishes are covered by plastic sheets (radomes) to keep out moisture. Microwave is a form of electromagnetic radiation with wavelengths shorter than other radio waves but longer than infrared waves.
Police car equipped with an LRAD-500X sonic weapon (Warsaw, Poland, 2011).. A directed-energy weapon (DEW) is a ranged weapon that damages its target with highly focused energy without a solid projectile, including lasers, microwaves, particle beams, and sound beams.
The first modern horn antenna in 1938 with inventor Wilmer L. Barrow. A horn antenna or microwave horn is an antenna that consists of a flaring metal waveguide shaped like a horn to direct radio waves in a beam. Horns are widely used as antennas at UHF and microwave frequencies, above 300 MHz. [1]
Radio bands where microwave antennas are commonly deployed in 2016 FCC [2]; C band: 4 to 8 GHz: 3.75 cm to 7.5 cm 4 GHz, 6 GHz X band: 8 to 12 GHz: 25 mm to 37.5 mm
Electric field Ex component of the TE31 mode inside an x-band hollow metal waveguide. A waveguide is a structure that guides waves by restricting the transmission of energy to one direction. Common types of waveguides include acoustic waveguides which direct sound, optical waveguides which direct light, and radio-frequency waveguides which ...
