The excitation of propagating THz surface plasmons on 1D plasmonic metamaterials with disorder is studied using convection electrons. The introduction of disorder is found to support non-Bloch surface plasmons and reduce the mode competition between the excited surface plasmons.
Due to the broad spectrum and versatility of electromagnetics, progress and new discoveries in this field have not made a uniform history. The same and similar phenomena are reinvented by researchers whose interests center on different frequency ranges. Surface waves make an illustrating example. Starting from the works of Sommerfeld and Zenneck, the theory of radio waves over ground was developed...
Subwavelength confinement and manipulation of light is of a great importance for imaging, sensing, high- resolution lithography, all-optical signal processing, as well as photonic funnels and superlenses. The diffraction limit, however, prevents such a confinement of optical radiation to the dimensions smaller than one half of the wavelength in the material. Conventional resolution-improvement techniques...
The feasibility of realizing an active Tera Hertz (THz) switch by utilizing artificially corrugated perfect conductor meta-materials is reported in this paper by demonstrating that the strongly localized THz spoof surface plasmon polariton (SSPP) modes can be easily controlled by changing the refractive index of dielectrics inside a longitudinal metallic structure with a periodic array of grooves...
We report on experimental realization of different metal-dielectric structures that are used as surface plasmon polariton waveguides and as plasmonic metamaterials. Fabrication approaches based on different lithographic and deposition techniques are discussed.
