High-mode spoof SPP of periodic metal grooves for ultra-sensitive terahertz sensing.
We report terahertz surface plasmon resonance (SPR) sensing based on prism-coupling to the spoof surface plasmon polariton (SSPP) mode existing on periodically grooved metal films. It was demonstrated that, except for the fundamental mode of the SSPP, there was also a higher mode SSPP wave when the depth of groove was larger. Both fundamental and high-order modes of SSPP could be used for terah...
متن کاملFrequency-dependent circular-polarization of terahertz chiral spoof surface plasmon polariton on helically grooved metallic wire
Chiral spoof surface plasmon polaritons in the terahertz region, resulting from a coherent superposition of TM and HE modes, can be generated by normally exciting helically corrugated metal wire with a linearly polarized Gaussian light. The handedness of the chiral SPP depends on the handedness of the helical groove. The chirality of the surface wave causes a spiral spatial extent of average po...
متن کاملBroadband Terahertz Sensing on Spoof Plasmon Surfaces
In this paper, we show that broadband spectral data can be experimentally extracted from corrugated metallic surfaces consisting of a linear array of subwavelength grooves supporting tightly confined spoof plasmons. Using a combination of the scattering edge coupling method and short-time Fourier transform, we are able to discern the group velocity characteristics of a spoof plasmon pulse, whic...
متن کاملAbstract—We propose a method to generate THz vector Bessel beams by converting spoof surface plasmon polaritons into a series of backward radiation titled towards the optical axis using a concentric metal corrugation
We propose a method to generate THz vector Bessel beams by converting spoof surface plasmon polaritons into a series of backward radiation titled towards the optical axis using a concentric metal corrugation structure. The proposed method enables replacing a conventional bulky axicon lens with a flat device and contributes to the implementation of integrated THz systems.
متن کاملSpoof surface plasmon based planar antennas for the realization of Terahertz hotspots
Novel spoof surface plasmon based terahertz (THz) antennas are realized using a few number of rectangular grooves perforated in ultrathin metal stripes and the properties of them, including both scattering cross sections and field enhancement, are numerically analyzed. The dependence of these properties on the incident angle and groove number is discussed and the results show that sharp resonan...
