Higher Order Geometrical Modeling and Higher Order Field/Current Modeling in FEM, MoM, and PO Simulations
نویسندگان
چکیده
Higher-order, large-domain electromagnetic simulations are presented based on the finite element method (FEM), method of moments (MoM), and physical optics (PO). The simulations combine higher order geometrical modeling and higher order field/current modeling, which is referred to as double-higher-order modeling. The examples demonstrate that accurate and efficient FEM, MoM, and PO simulations require both higher-order geometrical flexibility for curvature modeling and higher-order basis functions for field/current modeling in the same method. It is optimal to have the geometrical orders and current/field approximation orders of the elements entirely independent from each other, so that the two sets of parameters can be combined independently in a double-higher-order model.
