Ground-Plane Quasi-Cloaking for Free Space
Efthymios Kallos, Christos Argyropoulos, Yang Hao
Ground-plane cloak designs are presented, which minimize scattering of electromagnetic radiation from metallic objects in the visible spectrum. It is showed that simplified ground-…
A Radial-Dependent Dispersive Finite-Difference Time-Domain Method for the Evaluation of Electromagnetic Cloaks
Christos Argyropoulos, Yan Zhao, Yang Hao
A radial-dependent dispersive finite-difference time-domain (FDTD) method is proposed to simulate electromagnetic cloaking devices. The Drude dispersion model is applied to model t…
Enhancement of evanescent waves inside media with extreme optical anisotropy
Pavel A. Belov, Yan Zhao, Yang Hao +1
Significant enhancement of evanescent spatial harmonics inside the slabs of media with extreme optical anisotropy is revealed. This phenomenon results from the pumping of standing…
Full-wave finite-difference time-domain simulation of electromagnetic cloaking structures
Yan Zhao, Christos Argyropoulos, Yang Hao
This paper proposes a radial dependent dispersive finite-difference time-domain method for the modelling of electromagnetic cloaking structures. The permittivity and permeability o…
Magnification of Subwavelength Field Distributions at Microwave Frequencies Using a Wire Medium Slab Operating in the Canalization Regime
Pekka Ikonen, Pavel Belov, Constantin Simovski +2
Magnification of subwavelength field distributions using a wire medium slab operating in the canalization regime is demonstrated using numerical simulations. The magnifying slab is…
Accurate Modelling of Left-Handed Metamaterials Using Finite-Difference Time-Domain Method with Spatial Averaging at the Boundaries
Yan Zhao, Pavel Belov, Yang Hao
The accuracy of finite-difference time-domain (FDTD) modelling of left-handed metamaterials (LHMs) is dramatically improved by using an averaging technique along the boundaries of…
