Terahertz Devices with EMXT Structure Fabricated by MEMS

Abstract

Due to the micro-dimension of terahertz devices and antennas, it requires more stringent processing technology. Micro-Electro-Mechanical Systems (MEMS) used to fabricate terahertz functional devices and antennas is a good choice for the high accuracy, good consistence and low cost. In this paper, one approach to obtain antennas and passive devices in terahertz band is proposed, which based on electromagnetic crystal structure and MEMS technology. The band-pass filter, 90° bend waveguide and H-plane horn antenna operating at terahertz band are presented as examples. All of them have good agreement between simulation and measurement.
