Abstract

A higher-order finite element - boundary integral (FE-BI) method is presented to calculate the radar cross section (RCS) of body-of-revolution (BOR) geometries. The method is based on a finite element method (FEM) that uses higher-order nodal based scalar functions for the azimuthal field components and higher-order edge based vector basis for the transverse field. The FEM mesh is truncated with a boundary integral based on a first order method of moments (MoM). Such a method is void of spurious modes and more accurate than earlier first order formulations
