2. Microwave oven - Wikipedia

   en.wikipedia.org/wiki/Microwave_oven

   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. Microwave ovens heat foods quickly and efficiently ...

3. Electromagnetic spectrum - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_spectrum

   Electromagnetic spectrum. The electromagnetic spectrum is the full range of electromagnetic radiation, organized by frequency or wavelength. The spectrum is divided into separate bands, with different names for the electromagnetic waves within each band. From low to high frequency these are: radio waves, microwaves, infrared, visible light ...

4. Microwave transmission - Wikipedia

   en.wikipedia.org/wiki/Microwave_transmission

   Microwave transmission is the transmission of information by electromagnetic waves with wavelengths in the microwave frequency range of 300 MHz to 300 GHz (1 m - 1 mm wavelength) of the electromagnetic spectrum. Microwave signals are normally limited to the line of sight, so long-distance transmission using these signals requires a series of ...

5. Microwave - Wikipedia

   en.wikipedia.org/wiki/Microwave

   Microwave is a form of electromagnetic radiation with wavelengths shorter than other radio waves but longer than infrared waves. Its wavelength ranges from about one meter to one millimeter, corresponding to frequencies between 300 MHz and 300 GHz, broadly construed. [1][2]: 3 [3][4][5][6] A more common definition in radio-frequency engineering ...

6. Super high frequency - Wikipedia

   en.wikipedia.org/wiki/Super_high_frequency

   t. e. Super high frequency (SHF) is the ITU designation for radio frequencies (RF) in the range between 3 and 30 gigahertz (GHz). This band of frequencies is also known as the centimetre band or centimetre wave as the wavelengths range from one to ten centimetres. These frequencies fall within the microwave band, so radio waves with these ...

7. Ka band - Wikipedia

   en.wikipedia.org/wiki/Ka_band

   Radio bands. The Ka band (pronounced as either "kay-ay band" or "ka band") is a portion of the microwave part of the electromagnetic spectrum. The designation "K a -band" is from Kurz-above, which stems from the German word kurz, meaning "short". [1] There is no standard definition of Ka-band. IEEE Standard letter designations for Radar Bands ...
