摘要：
A polarization-sensitive terahertz switch is presented in this work. The device works passively in the transmission mode and shows different transmission behaviors for the two orthogonal polarizations. The operation central frequency and bandwidth of the switch are 926GHz and 140GHz, respectively. The switching contrast of the device is 9.3dB for y-polarization and 28.5dB for x-polarization at its center frequency. The impact of the geometrical parameters of the switch on its performance is briefly discussed.
