Finite Element Modeling of Anisotropic Half-Space Problems by a Simple Mesh Truncation Scheme

Kuzuoğlu, Mustafa
Anisotropic half-space problems are modeled with finite element method with a simple mesh truncation scheme based on the locally-conformal PML method. The PML is simply implemented by just using complex coordinates inside an anisotropic medium without introducing additional anisotropy and without modifying the finite element formulation. This approach is useful to model electromagnetic radiation and scattering from structures embedded within arbitrary anisotropic media. Simulation results are demonstrated to measure the performance of the model.
