- W4387521252 abstract "Abstract High refractive index dielectric metasurfaces give rise to unprecedented control on light manipulation such as control of phase, polarization and amplitude giving rise to interesting properties such as directional beam steering, polarization detectors, sensors, etc. Dielectric metasurfaces of sub-wavelength dimensions have tremendous applications in the field of optics such as negative refractive index, cloaking, perfect absorbers and reflectors. Study of light matter interactions in such materials have gained impetus due to formation of novel states like anapoles and transparent states obtained by interference between resonant electric, magnetic and higher order modes. In this article, we investigate light-matter interaction of array of periodic dielectric metasurfaces made from high refractive index Tellurium in cubic geometries and study its electromagnetic response as a function of lattice constant, angle of incidence and angle of polarization. More specifically, we observed a non-resonant transparent state at 60.69 THz, which is independent of lattice-constant and polarization of the input radiation. Moreover, this state shows a high transmission for a broad range of incident angles with potential applications as optical filters. and depends on the incident polarization, thus acting as a perfect polarization detector. Detailed investigations of scattering parameters, spatial distribution of electric and magnetic fields in the near- and far-field regions and detailed multipole analysis are carried out to analyze the electromagnetic response of the metasurface." @default.
