It’s said that the atomic bomb ended WW2 but the Cavity Magnetron won the war. The invention of this palm-sized device gave first the British and then the Americans a microwave radar generator that was 1000 times more powerful than anything they had before and enabled small high power radar to be fitted to planes, ships, and vehicles. This transformed the war and swung it for the allies in Europe and the US in the pacific. This is the story of the Cavity Magnetron.
