WebPowerful terahertz sources. TeraSense has mastered technology to manufacture powerful electro-vacuum terahertz sources. The technology resides on a backward wave oscillator effect. An electron gun emits an electron beam that is longitudinally focused by an external magnetic field. The magnetic field is created by a permanent NdFeB magnet. WebIt is a special type of vacuum tube used to produce microwave signals in the range of Terahertz (THz). Backward wave oscillator belongs to the group …
