Abstract

An asymptotic solution method for three-dimensional electromagnetic field problem inside and outside an imperfectly conducting cusp is proposed. Implementation of the method leads to a boundary value problem with singular boundary conditions. This problem can be solved numerically using the partition of unity method. Wave propagation in an L-shaped waveguide is modeled as an example
