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.

3. Microwave - Wikipedia

   en.wikipedia.org/wiki/Microwave

   Microwave wavelengths in the centimeter range were required to give the small radar antennas which were compact enough to fit on aircraft a narrow enough beamwidth to localize enemy aircraft. It was found that conventional transmission lines used to carry radio waves had excessive power losses at microwave frequencies, and George Southworth at ...

4. Over-the-horizon radar - Wikipedia

   en.wikipedia.org/wiki/Over-the-horizon_radar

   The frequency of radio waves used by most radars, in the form of microwaves, travel in straight lines.This generally limits the detection range of radar systems to objects on their horizon (generally referred to as "line of sight" since the aircraft must be at least theoretically visible to a person at the location and elevation of the radar transmitter) due to the curvature of the Earth.

   In 1947, the first commercially produced microwave oven was about 6 feet tall, weighed about 750 lbs, and cost about $5,000 (equivalent to $68,227 in 2023). In 1967 the first more affordable, $495 (equivalent to $4,523 in 2023), and reasonably sized (counter-top) Radarange brand microwave oven was made available for sale, [ 2 ] produced by ...

6. Amana Corporation - Wikipedia

   Amana was acquired in 1965 by Raytheon, [7] which had invented the microwave oven in 1947, and introduced the commercial Radarange Model 1611 in 1954. [5] In 1967, Amana introduced a consumer model of the Radarange , the first popular microwave designed for home use.

7. S band - Wikipedia

   en.wikipedia.org/wiki/S_band

   The largest use of this band is by Wi-Fi networks; the IEEE 802.11b and 802.11g standards use the 2.4 GHz section of the S band. These are the most widely used computer networks in the world, used globally in home and small office networks to link desktop and laptop computers, tablet computers, smartphones, smart TVs, printers, and smart speakers together and to a wireless router to connect ...
