Webb7 okt. 2024 · Furthermore, the function of the spoof SPPs switch can be realized by increasing the number of incident aperture waveguides. The simple structure and small size, means that this multi-frequency splitter and switch can be conveniently integrated into THz sensing or THz communication systems. Webbperformance of THz spoof SPPs and effectively manipulating them still remain as challenges. Inspired by this, in this paper, we theoretically and experimentally demonstrate a THz spoof SPP waveguide structure consisting of periodic metallic rectan-gular pillars. Based on our recently developed scanning near- peace of mind vector

WebbPlasmonic sensing techniques offer fast, label-free analysis, and hold advantages over labelling techniques such as ELISA (enzyme-linked immunosorbent assay). Plasmonic Sensors and their Applications examines the development and use of highly sensitive and selective plasmonic sensing platforms in chemistry, biotechnology, and medicine. Webb8 dec. 2024 · The spoof SPPs (SSPPs) possess natural SPP-like dispersion properties and strong confinement of EM fields, and therefore is a special kind of slow waves with a propagation constant (kspp) larger than that in free space (k0). Metasurfaces have been developed to support the propagation of SSPP waves in a various of circumstances. Webb17 maj 2024 · Our SSP-based terahertz SPR sensor with the resonance frequency around 0.404 THz provides a maximum sensitivity of 335 GHz/RIU and a detection limit less … sdr direction finder
