TERAHERTZ BAND-PASS FILTER

摘要

The present invention relates to the field of terahertz communication. Provided is a terahertz band-pass filter comprising a filter unit structure, the filter unit structure comprises a first resonator, a dielectric layer and a second resonator which are sequentially laminated. The first resonator comprises a metal plate provided with a hollow pattern, the hollow pattern comprises a first bar shape and a second bar shape extending perpendicularly to the first bar shape from both ends of the first bar shape, and the first resonator and the second resonator have the same structure. The present invention achieves the wide filter band of the terahertz band-pass filter by adopting a first resonator-dielectric layer-second resonator provided with a hollow pattern to form the filter unit structure, and can be applicable to broadband communication.
