Elemental matrices for the finite element method in electromagnetics with quadratic triangular elements

摘要

The finite element method has become a preeminent simulation technique inelectromagnetics. For problems involving anisotropic media and metamaterials,proper algorithms should be developed. It has been proved that discretizing inquadratic triangular elements may lead to an improved accuracy. Here we presenta collection of elemental matrices evaluated analytically for quadratictriangular elements. They could be useful for the finite element method inadvanced electromagnetics.
