Full-wave parallel dispersive finite-difference time-domain modeling of three-dimensional electromagnetic cloaking structures
Yan Zhao, Yang Hao
A parallel dispersive finite-difference time-domain (FDTD) method for the modeling of three-dimensional (3-D) electromagnetic cloaking structures is presented in this paper. The pe…
Manipulating the Loss in Electromagnetic Cloaks for Perfect Wave Absorption
Christos Argyropoulos, Efthymios Kallos, Yan Zhao +1
We examine several ways to manipulate the loss in electromagnetic cloaks, based on transformation electromagnetics. It is found that, by utilizing inherent electric and magnetic lo…
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…
Subwavelength internal imaging by means of the wire medium
Yan Zhao, Pavel A. Belov, Yang Hao
Evanescent wave amplification is observed, for the first time to our knowledge, inside a half-wavelength-thick wire medium slab used for subwavelength imaging. The wire medium is a…
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…
