Parameter Estimation for Dielectric Media Variations Based on the FDTD Method and the Monge–Kantorovich Mass Transfer Problem
Georgios G. Pyrialakos,Nikolaos V. Kantartzis,Tadao Ohtani,Yasushi Kanai,Theodoros D. Tsiboukis +4 more
TL;DR: In this article, an efficient and consistent methodology is developed for the precise evaluation of unknown dielectric permittivity media parameters involved in the design of 3-D waveguide structures.

A Nonstandard Path Integral Model for Curved Surface Analysis
TL;DR: A nonstandard path integral (PI) model for the NS-FDTD method is proposed, based on the fact that the PI form of Maxwell’s equations is fairly more suitable to treat objects with smooth surfaces than the differential form.
Homogenization of 3D metamaterial particle arrays for oblique propagation via a point-dipole analysis
TL;DR: In this paper, a rigorous technique for the consistent calculation of the effective parameters of infinite three-dimensional metamaterial particle arrays in the realistic case of oblique wave propagation is presented, where the extracted polarizabilities of the consisting scatterer and the numerically retrieved wavenumber for the obliquely propagating electromagnetic waves are systematically inserted into a properly modified first-principles homogenization technique.

Consistent Integral Equation Modeling of Cloaking Planar Microstrip Antennas
Athanasios N. Papadimopoulos,Nikolaos L. Tsitsas,Constantinos A. Valagiannopoulos,Nikolaos V. Kantartzis,Christos S. Antonopoulos,Theodoros D. Tsiboukis +5 more
TL;DR: In this paper, an efficient integral equation method is developed for the response and scattering characteristics of cloaked 2-D planar microstrip receiving antennas, where the desired low-profile operation of the antenna is achieved by overlaying a superstrate slab atop the antenna.
