Proceedings ArticleDOI
New considerations on electromagnetic energy in antenna near-field by time-domain approach
TL;DR: In this article, a finite-difference time-domain (FDTD) simulation strategy for calculating reactive energy near radiating structures is described, and new aspects pertaining to time-evolution and visualization of the near-field energy distributions are described, that can be tackled with this FDTD-based methodology.
Journal ArticleDOI
Approximated Complementary Cloak With Diagonally Homogeneous Material Parameters Using Shifted Parabolic Coordinate System
TL;DR: In this paper, a parabolic shaped complementary cloak is proposed which makes the object invisible by reducing its scattering under different incidence angles of electromagnetic wave, which is based on transforming a line segment into an enclosed space that is surrounded by the core region.
Journal ArticleDOI
Synthesis and microwave characterisation of (Zr 0.8 Sn 0.2) TiO 4 -epoxy composite and its application in wideband stacked rectangular dielectric resonator antenna
TL;DR: In this article, a two-layer rectangular dielectric resonator antenna using coaxial excitation for obtaining wideband performance was proposed, and the effect of antenna parameters like length, width and probe length were investigated using Ansoft's high-frequency structure simulator (HFSS) software.
Journal ArticleDOI
Three‐element multilayer multipermittivity cylindrical dielectric resonator antenna for wideband applications with omnidirectional radiation pattern and low cross‐polarization
TL;DR: In this article, a three-element multilayer multi-permittivity (MLMP) cylindrical dielectric resonator antenna (CDRA) is proposed for wideband application.
