Electromagnetic wave generator and optical shutter using the same

摘要: An electromagnetic wave generator for outputting wideband waves, including terahertz (THz) band and controlling wavelengths of the output waves an optical shutter are provided. The includes two electrodes that separately face each other, a chargeable particle disposed between electrodes, chamber to surround electrodes. When DC voltages applied generate electric field may be charged. Then, reciprocates waves. A wavelength controlled by adjusting potential difference
