Abstract :
This paper presents a series solution for the longitudinal electromagnetic fields at arbitrary dielectric corners. We apply versions of the method that are up to sixth-order accurate to our recently proposed full vector boundary element method (BEM) mode solver. Our results indicate that our previous formulation models corner fields with high precision.
