基于镍人工表面等离子激元的W波段波导终端
A W-band waveguide termination based on nickel SSPPs
摘要
Abstract
The electromagnetic losses of nickel waveguides in the submillimeter wave frequency band are measured,and a waveguide terminator based on nickel Spoof Surface Plasmon Polaritons(SSPPs)is designed for multi-port waveguide device measurements and power divider port isolation.The waveguide employs a simple and compact antisymmetric rectangular probe structure to efficiently couple electromagnetic energy from the waveguide to a microstrip,which is then transmitted to a comb-like SSPPs terminator.The microstrip circuit and SSPPs circuit are fabricated on a quartz substrate,with the metal circuit being electroplated metal nickel.Utilizing the band-stop characteristics of SSPPs and the high-frequency high-loss properties of metal nickel,the attenuation and absorption of electromagnetic energy are achieved.The proposed nickel SSPPs waveguide terminator is experimentally validated in the W-band(75～110 GHz).The experimental results indicate that the Return Loss of this waveguide terminator exceeds 15 dB across the entire W-band,with a corresponding electromagnetic absorption rate of over 96.8%.关键词
