Paper Abstract

We proposed a simple scheme to manipulate the position of the reflected terahertz wave beam based on the prism/liquid crystal structure. Both the stationary-phase method and finite element method are used to analyze and simulate the characteristics of the proposed device. To give comprehensive understanding, the position of the reflected terahertz wave beam is verified in simulation by using the COMSOL Multiphysics software. Numerical calculation results show that the proposed terahertz wave switch a high extinction ratio (35dB for TE polarization and 30dB for TM polarization). This provides an attractive way for creating a simple structure and compact size terahertz wave switch with acceptable extinction ratio.
