High Power Microwaves

According to Jack Welch, "We often measure everything and I do not understand anything." So the government decided to carefully study high power microwaves. In his thesis I will discuss with you high power microwave, its application, comparison of two different types, some history and findings. "High power microwave (HPM) is an incorrect term used in some communities, and at the Department of Defense it is primarily intended to generate high peak power pulses across narrowband (coherent) electromagnetic radiation It is used.

There are two kinds of high power microwave and high energy laser. High power microwave radiates electric microwave radiation pulses at a wide angle, but high energy lasers use one of two laser mechanisms to direct high energy focused low energy beam: chemical fuel Electrical. Chemical lasers are the only system that generates megawatt output. However, they require special handling and are generally driven by a mixture of toxic chemicals that are not popular in the United States. Another reason is the lack of significant strategic value of directional energy weapons as they rely on external / independent power supply: almost unlimited magazine

In 1945, Percy Spencer, an American self-taught engineer in Howland, Maine, tried over the specific heating effect of the high power microwave beam. When Raytheon hired him, he noticed that the microwave oven of the active radar device he was using began melting the chocolate bar in his pocket. The first food specially cooked by Spencer's microwave oven was popcorn and the second was an egg and exploded in front of the experimenter. In order to confirm his finding, Spencer could not escape by supplying the microwave power of the magnetron to the metal box, creating a high density electromagnetic field. When food is put into a box with microwave energy, the temperature of food rises rapidly. On 8th October 1945, Raytheon filed a US patent application for Spencer's microwave cooking process, and an oven with a magnetron to heat food using microwave energy for testing It was immediately placed in a restaurant in Boston.
