【 摘 要 】

THz surface plasmon are decayed exponentially when propagating along the surface of a semiconductor. A metal razor bladeis used to couple THz surface plasmon to THz waves at different position on the surface of an indium antimonide wafer. Thus the intensity of the output THz wave is modulated.
