Abstract Photonic crystals (PhC) formed by 2-D non-Moiré geometries are realized in this work. Non-Moiré (NM) tiles are the contours of trigonometric functions that generate exciting shapes and geometries. Photonic bandstructure calculations reveal

Bulk Dirac Semimetal (BDS) - a three-dimensional counterpart of graphene, prominently known for its topologically protected linear dispersion energy bands embraces remarkable plasmonic responses at terahertz (THz) frequencies, which can be well capit

A two-dimensional transformational electromagnetic (T-E) device formed by configuring a circular disc with a Fermat spiral is realized. By tuning the phase of the emanating wave in the T-E medium, antenna switching and beam steering are made possible

A bilayered-twisted Fermat's spiral chiral metamaterial (FSCMM) is proposed for the realization of circular polarization of far-infrared waves and polarization filters. It is demonstrated through full-wave simulations that the proposed FSCMM can conv

Advanced Electromagnetics, Vol 2, Iss 1 (2013)
Beam steering due to anomalous dispersion at higher photonic bands in dielectric photonic crystal is reported in this work. Based on this concept, directional cloak is designed that conceals a larger dimensional scattering object against the normal i
