Abstract :
The electric field of the modes of rectangular dielectric waveguides is known to diverge in the corners of the waveguide. An accurate numerical computation of the vector mode fields for a sample waveguide exhibits clear signs of this divergence. The divergence makes the design of rapidly converging numerical algorithms for vector mode field computations difficult
