A new method of modeling electromagnetic waves by the finite element method is presented. The method is based on a numerical formulation in which different orders of polynomials are used to approximate the three different components of either the electric or the magnetic field vectors. It provides a reliable procedure for the finite element solution of three-dimensional electromagnetic field problems. Heretofore, such solutions were plagued by the presence of spurious modes. The new method is applied to the analysis of fields in resonant electromagnetic cavities. Keywords: Bistatic scattering; Finite element analysis; Cloning; Measurements.
