Hybrid Higher Order FEM-MoM Analysis of Continuously Inhomogeneous Electromagnetic Scatterers
نویسنده
چکیده
A novel higher order entire-domain finite element technique is presented for accurate and efficient fullwave three-dimensional analysis of electromagnetic structures with continuously inhomogeneous material regions, using large (up to about two wavelengths on a side) generalized curved hierarchical curl-conforming hexahedral vector finite elements (of arbitrary geometrical and fieldapproximation orders) that allow continuous change of medium parameters throughout their volumes. The results demonstrate considerable reductions in both number of unknowns and computation time of the entire-domain FEM modeling of continuously inhomogeneous materials over piecewise homogeneous models.

Analysis of Electromagnetic Scatterers using Hybrid Higher Order FEM - MoM Technique
A higher order large-domain hybrid finite element – method of moments (FEM-MoM) technique is presented.

A benchmark example of analysis of a scatterer with pronounced curvature at resonant frequency is given, demonstrating accuracy and robustness of the presented hybrid technique.
متن کاملApplication of Hierarchical Higher-order Tangential Vector Finite Elements in a Hybrid Fem/mom Method
Hybrid FEM/MoM methods combine the finite element method (FEM) and the method of moments (MoM) to model inhomogeneous unbounded problems. These two methods are coupled by enforcing field continuity on the boundary that separates the FEM and MoM regions. Hierarchical higher-order tangential vector finite elements (TVFE’s) are of practical interest because they can be easily combined with low-ord...

Hybrid FEM/MoM methods combine the finite element method (FEM) and the method of moments (MoM) to model inhomogeneous unbounded problems. These two methods are coupled by enforcing field continuity on the boundary that separates the FEM and MoM regions. There are three ways of formulating hybrid FEM/MoM methods: outward-looking formulations, inward-looking formulations and combined formulations...
