A finite element method for solving electromagnetic scattering problems

A novel finite element formulation of the electromagnetic scattering problem which can be considered a generalization of the unimoment method is presented. In order to validate the method, the authors apply it to two simple problems with known analytical solutions. The first problem is scattering from a perfectly conducting circular cylinder, in free space, due to an incident plane wave. Also considered is the problem of scattering from a dielectric circular cylinder, in free space, due to an incident plane wave.<>
