Is there a way to solve in Matlab an antenna radiation problem for an axisymetric radiator?

Hello,

Is there a way to solve in Matlab an antenna radiation problem for an axisymetric radiator?

For example a conical horn. Looking for radiation patterns and return loss. This is a simple problem.

The Body of Revolution method (BOR), where applicable, is able to convert a 3D problem to a 2D problem, so I am looking for an inexpensive solver. I know that Malab has some electromagnetic FEM 3D solver, but I am not aware of the exisitng of a Matlab solver for axisymmtric bodies.

Thank you
