Abstract
This paper reports the design, analysis, and characterization of a multi-bandnotch filter using plasmonic metamaterial concept. The proposed design comprises of a unique arrangement of spoof surface plasmons polaritons (SSPP) based planar transmission line and spoof surface whispering gallery mode resonator (SS-WGM). Due to the slowwave nature of the SS-WGM resonator, the designed filtering structure provides high-Q and sharp bandnotch response. This enables the proposed filtering structure to be used in wireless transceiver system to avoid spurious harmonics and intermodulation components.
