HOFEM: Higher order finite element method simulator for antenna analysis
This document presents the application of a new electromagnetic in house parallel EM simulator to the antenna analysis. The simulator is included in the commercial software HOBBIES. HOFEM makes use of a weak formulation based on double curl vector wave equation discretized with the higherorder isoparametric curl conforming tetrahedral and triangular prismatic finite element rigorous implementations of Nedelec's first family of elements. These implementations together with an appropriate hp adaptivity technique provide very accurate field approximations. A non standard mesh truncation technique, FE IIEE (Finite Element Iterative Integral Equation Evaluation) for open region problems is also implemented providing an arbitrarily exact radiation boundary condition while retaining the original sparse structure of the FEM matrices. A numerical example is presented showing the reliability, performance and versatility of the solver for the antenna analysis.
