Flexible composites containing BaTiO 3 nanoparticles into Gelatin bio-polymer matrix were
designed and investigated. Following the idea that the electric field concentration in …

Despite being among the most common medical procedures, needle insertions suffer from a
high error rate. Impedance measurements using electrode‐equipped needles offer promise …

The a priori known field behavior in the vicinity of simple, not grid conformal geometrical
shapes is used to derive new approaches for the material averaging in the two-dimensional …

During the operation of an x-ray device, high voltage stresses increase risk of dielectric
breakdown. It is critically important that these systems are designed so that the magnitude of …

The magnitude of the electric field or electric field stress can become very large in high-
voltage applications. These devices must be designed such that the electric field stresses …

This paper is devoted to the study of the features of artificial gyrotropic magneto-dielectric
layer with two-dimensional periodicity. Such a layer can be used in the development of the …

A numerical method for symmetric cylindrical and spherical waveguide eigenvalue problems
is presented using local discontinuous Galerkin (LDG) method based on polar coordinates …

We consider in this thesis a correction technique using finite element and finite difference
methods applied to elliptic problems defined on re-entrant corner domains in two …

Discrete geometric method (DGM) is implemented for solving Maxwell's equations on
plasmonic structures. Surface plasmons introduce non-derivable field components at the …

We propose a numerical method for computation of singular electromagnetic fields in a
polyhedral non-convex cavity. The method is based on edge conforming elements …
