2. Microwave - Wikipedia

   en.wikipedia.org/wiki/Microwave

   Microwaves are especially suitable for this use since they are more easily focused into narrower beams than radio waves, allowing frequency reuse; their comparatively higher frequencies allow broad bandwidth and high data transmission rates, and antenna sizes are smaller than at lower frequencies because antenna size is inversely proportional ...

3. Electromagnetic spectrum - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_spectrum

   Microwaves are the main wavelengths used in radar, and are used for satellite communication, and wireless networking technologies such as Wi-Fi. The copper cables ( transmission lines ) which are used to carry lower-frequency radio waves to antennas have excessive power losses at microwave frequencies, and metal pipes called waveguides are used ...

4. Super high frequency - Wikipedia

   en.wikipedia.org/wiki/Super_high_frequency

   Super high frequency (SHF) is the ITU designation [1] [2] 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.

5. 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 in a process known as dielectric heating .

7. 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 ...
