Abstract
Terahertz transmission of several metallic mesh structures is studied based on the finite differential time domain (FDTD) method. The terahertz filtering properties of these metallic meshes are analyzed by the numerical simulation. The shape and size dependence of terahertz transmission of these metallic structures are illustrated. The numeric results show that the terahertz transmission of these metallic meshes have various frequency selectivity. The design of terahertz filters for the different resonance frequencies is presented based on the above simulation. This work provides a good reference for the design and manufactures of terahertz filter.
