WebWe have demonstrated both numerically and experimentally a 2D plasmonic metamaterial the unit cell of which comprised an Archimedean spiral with a C-shaped resonator. Such metasurface enables the excitation of spoof localized plasmon resonances (LPRs) in the terahertz frequency range, similar in properties to the familiar LPRs in the visible range. … WebApr 9, 2024 · [66, 67] The associated shift of the absorption edge leads to a change in the refractive index, which is the maximum for photon energies near the absorption band edge. With QCSE, the modulation frequency is theoretically limited by the dielectric relaxation rate and practically limited by RC terms that have to be minimized in the design and ...
