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 rotate and produce thermal energy (heat) in a process known as dielectric heating.

3. Ku band - Wikipedia

   en.wikipedia.org/wiki/Ku_band

   The K u band (/ ˌ k eɪ ˈ j uː /) is the portion of the electromagnetic spectrum in the microwave range of frequencies from 12 to 18 gigahertz (GHz). The symbol is short for "K-under" (originally German: Kurz-unten), because it is the lower part of the original NATO K band, which was split into three bands (K u, K, and K a) because of the presence of the atmospheric water vapor resonance ...

4. C band (IEEE) - Wikipedia

   en.wikipedia.org/wiki/C_band_(IEEE)

   The C band is a designation by the Institute of Electrical and Electronics Engineers (IEEE) for a portion of the electromagnetic spectrum in the microwave range of frequencies ranging from 4.0 to 8.0 gigahertz (GHz). [1] However, the U.S. Federal Communications Commission C band proceeding and auction, designated 3.7–4.2 GHz as C band. [2]

5. Bandwidth (signal processing) - Wikipedia

   en.wikipedia.org/wiki/Bandwidth_(signal_processing)

   the width of the range of some other phenomenon, e.g., a reflection, the phase matching of a nonlinear process, or some resonance; the maximum modulation frequency (or range of modulation frequencies) of an optical modulator; the range of frequencies in which some measurement apparatus (e.g., a power meter) can operate

6. Microwave - Wikipedia

   en.wikipedia.org/wiki/Microwave

   A microwave oven passes microwave radiation at a frequency near 2.45 GHz (12 cm) through food, causing dielectric heating primarily by absorption of the energy in water. Microwave ovens became common kitchen appliances in Western countries in the late 1970s, following the development of less expensive cavity magnetrons. Water in the liquid ...

7. Horn antenna - Wikipedia

   en.wikipedia.org/wiki/Horn_antenna

   The corrugated horn invented by Kay in 1962 has become widely used as a feed horn for microwave antennas such as satellite dishes and radio telescopes. [9] An advantage of horn antennas is that since they have no resonant elements, they can operate over a wide range of frequencies, a wide bandwidth.
