TL;DR: An overview of the finite-element method (FEM) as applied to electromagnetic scattering and radiation problems with particular emphasis on new developments over the past five years relating to feed modeling, parallelization, and mesh truncation.

TL;DR: The asymptotic waveform evaluation (AWE) method is one approach to construct a reduced order model of the input impedance or other useful electromagnetic parameters, such as S parameters and far field pattern as mentioned in this paper.

TL;DR: An edge-based hybrid finite element-boundary integral (FE-BI) formulation using tetrahedral elements is described for scattering and radiation analysis of arbitrarily shaped cavity-backed patch antennas.

TL;DR: In this article, the magnetic properties of ferrite materials have been used for electromagnetic applications, particularly those involving printed microwave circuits, and their properties can be easily changed with frequency, including non-reciprocal effects, frequency tuning by changing external biasing, polarization diversity using a single element, and various other useful properties.

TL;DR: In this article, an anisotropic absorber for truncating finite element meshes is investigated. But the interface of the absorber is made reflectionless by choosing /spl epsiv/sub r/ and /spl mu//sub 4/ to be complex diagonal tensors.
