3D hp-Adaptive Finite Element Simulations of a Magic-T Electromagnetic Waveguide Structure

This paper employs a 3D hp self-adaptive grid-refinement finite element strategy for the solution of a particular electromagnetic waveguide structure known as Magic-T. This structure is utilized as a power divider/combiner in communication systems as well as in other applications. It often incorporates dielectrics, metallic screws, round corners, and so on, which may facilitate its construction...

hp-ADAPTIVE 3D FINITE ELEMENT PACKAGE

The paper presents a description of par3Dhp a 3D, parallel, fully automatic hp-adaptive finite element code for elliptic and Maxwell problems. The parallel implementation is an extension of the sequential code 3Dhp90, which generates, in a fully automatic mode, optimal hp meshes for various boundary value problems. The system constitutes an infrastructure for a class of parallel hp adaptive com...

TM Electromagnetic Scattering from Multilayered Dielectric Bodies – Numerical Solution

An integral equation approach is derived for an electromagnetic scattering from an M multilayered dielectric domain. The integral equation is valid for 2D and 3D Helmholtz equation. Here we show the numerical solution for the 2D case by using the Nyström method. For validating the method we develop a mode matching method for the case when the domains are multilayered circular cylinders and give...

Electromagnetic scattering from anorthotropic

We investigate electromagnetic wave propagation in an inhomogeneous anisotropic medium. For the case of an orthotropic medium we derive the Lippmann-Schwinger equation, which is equivalent to a system of strongly singular integral equations. Uniqueness and existence of a solution is shown and we examine the regularity of the solution by means of integral equations. We prove the innnite Fr echet...
