DOI: 10.1007/s11468-020-01233-4
Abstract: We propose and numerically demonstrate a low-loss deep-subwavelength plasmonic metasurface that exhibits strong optical transmission at near-infrared wavelengths and concomitantly high electrical conductivity. The efficient realization of these two contrasting functionalities without a severe trade-off… read more here.

DOI: 10.1063/1.5087027
Abstract: Metasurfaces can manipulate optical wavefronts by locally shifting the phase of incident light with metallic or dielectric optical nanoresonators that are generally arranged on a lattice with subwavelength spacing. However, such conventional metasurfaces inevitably generate… read more here.

DOI: 10.1364/oe.460924
Abstract: In this paper, we study TEM-wave propagation inside a hollow coaxial waveguide filled with an inhomogeneous metamaterial composite, with a graded transition between a right-handed material (RHM) and an impedance-matched left-handed material (LHM). The graded… read more here.
