2. Microwave radiometer - Wikipedia

   en.wikipedia.org/wiki/Microwave_radiometer

   Review articles, [7] [8] and a detailed online handbook [9] are available. Microwave spectrum: The black lines show the simulated spectrum for a ground-based receiver; the colored lines are the spectrum obtained from a satellite instrument over the ocean measuring at horizontal (blue) and vertical (red) linear polarization.

3. 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 .

4. 2.4 GHz radio use - Wikipedia

   en.wikipedia.org/wiki/2.4_GHz_radio_use

   Most domestic microwave ovens operate by emitting a very high power signal in the 2.4 GHz band. Older devices have poor shielding, [10] and often emit a very "dirty" signal over the entire 2.4 GHz band. [a] This can cause considerable difficulties to Wi-Fi and video [12] transmission, resulting in reduced range or complete blocking of the signal.

5. ISM radio band - Wikipedia

   en.wikipedia.org/wiki/ISM_radio_band

   The bands are still widely used for these purposes. For many people, the most commonly encountered ISM device is the home microwave oven operating at 2.45 GHz which uses microwaves to cook food. Industrial heating is another big application area; such as induction heating, microwave heat treating, plastic softening, and plastic welding processes.

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. Radio spectrum - Wikipedia

   en.wikipedia.org/wiki/Radio_spectrum

   A radio band is a small frequency band (a contiguous section of the range of the radio spectrum) in which channels are usually used or set aside for the same purpose. To prevent interference and allow for efficient use of the radio spectrum, similar services are allocated in bands.
