Microwaves are the principal carriers of high-speed telegraphic data transmissions between stations on earth like the television, telephone, or a fax machine. Satellites provide communication links via microwave radio. Various types of microwave generators and amplifiers have been developed. Vacuum tube devices, the klystron, and the magnetron are all examples. These antennas can be established between any 2-land bases.
Microwave ovens use high-frequency electromagnetic waves to cook foods.
Microwave energy is preferred in dealing with ceramics because the powder remains active while being heated.
