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, produced by Amana (a division of Raytheon). [4] Spencer became Senior Vice President and a Senior Member of the Board of Directors at Raytheon. He received 300 patents during his ...
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 .
The Amana Corporation is an American brand of household appliances. It was founded in 1934 by George Foerstner as the Electrical Equipment Co. in Middle Amana, Iowa, to manufacture commercial walk-in coolers. The business was later owned by the Amana Society and became known as Amana Refrigeration, Inc. [2] It is now owned by the Whirlpool ...
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 ...
The second segment of White Alice was a pair of TD-2 microwave radio links that supported the Ballistic Missile Early Warning System (BMEWS) at Clear Air Force Station. This section provided two routes from Alaska to NORAD in Colorado, for this reason it was also known as the Rearward Communications System . [ 3 ]
