An approach, based on the finite element method (FEM), is used for evaluating the electromagnetic field distribution in a class of E-plane metal insert filters, operating in the Ka-band. Artificial boundary conditions are inserted directly in a functional, enabling a solution of the scalar wave equation by finite element method.The scattering parameters of the filter, the electromagnetic field and, therefore, the current distributions on the thin metal inserts are computed. Then, the power dissipated in the metallic septa, which is one of the major limitations for the maximum CW-power that can be handled by these types of filter, is evaluated using a perturbational approach. Finally, the maximum field intensity is determined, allowing an estimate of the maximum peak power that these structures can handle.
