人工表面等离子体的电容耦合带通滤波器
Capacitive-coupled bandpass filters based on spoof surface plasmonpolaritons
摘要
Abstract
A capacitive-coupled bandpass filter based on the spoof surface plasmonpolaritions(spoof SPPs) was presented.The coupling structure of the proposed filter was composed with a series of metal hole diamond structure units which were arranged in the transmission direction at intervals.An adiabatic transition was designed to effectively couple energy into spoof SPPs waveguides.From the dispersion relationship,the diamond hole metal strips could support spoof SPPs modes when the operating frequency was less than the cutoff frequency.The simulation results show that the 3 dB bandwidth of the filter is from 11.6 GHz to 18.3 GHz.Due to its simple and compact structure,it is easy to integrate the proposed filter into the microwave integrated system.It will play an important role in the follow-up development of microwave plasmonic integrated circuits and systems.关键词
