Abstract :
A novel compact sub-terahertz wave switch based on photonic crystals is proposed. We have investigated the performance of the proposed sub-terahertz wave switch by using plane wave expansion and finite-difference time-domain method. The numerical results show that an excellent sub-terahertz wave switch at a frequency of 0.1THz is achieved. The proposed sub-terahertz wave switch has a high extinction ratio of -40dB, and small size of 6.811mm. It has a potential application to sub-terahertz wave communication systems.
