摘要
We designed and fabricated a millimeter plasmonic chip consisted of coplanar waveguide (CPW) and plasmonic waveguide with one corrugated disk resonator (CDR). The spoof localized surface plasmon (LSP) resonance modes can be excited by the interaction between plasmonic waveguide and CDR. Fundamental and higher order sharp spoof LSP resonances (from dipole to dodecapole) were observed in the transmission coefficient spectrum. The Q-value as high as 268.3 (octupole) was experimentally obtained. Experimental results show good agreement with theoretical and simulated ones. All the results may have potential applications in microchip based sensing and filtering.
