Abstract :
We present in this paper an approach for the modeling of open boundary microwave problems in the frequency domain by using high order 2D mixed elements conforming in H(curl). The Galerkin formulation for the vector wave equation in two dimensions is used to discretize the problem. The analysis region is truncated using a 2D vector absorbing boundary condition that satisfies the Sommerfeld radiation condition at infinity. This modeling is applied to scattering problems or to open ended waveguides
