Abstract

This paper presents coordinate transformation techniques for solving low-frequency electromagnetic boundary value problems involving electrically-small geometrical features. The major motivation is to eliminate the need for fine mesh and to allow uniform and easy-to-generate meshes by placing transformation media into the computational domain. A salutary feature of the proposed methods is the capability to handle arbitrarily-shaped geometries by using a 'single' mesh and by changing only the constitutive parameters inside the matematerial layer. Several numerical simulations are illustrated in the context of finite element solution of electromagnetic scattering problems.
