The characteristic equation for an optical waยจeguide with a hypocycloidal cross section is obtained. This cross section can be thought of as haยจing the shape of a distorted square and leads to a tolerance analysis for deformation in a square waยจeguide. The complex geometry makes the analysis of mode
With the use of the scalar field approximation a study has been made of a guide haยจing a shape of the lemniscate of Bernoulli as its cross section. This structure represents approximately the situation when two cores are embedded in the same cladding. This is often done in ( practice. In this case o
MoM solutions. In Section II, a few results at a moderately high frequency were presented, which showed excellent agreement between the standard MoM code and the hybrid method. These hybrid results, while interesting, are not new given the wide use and maturity of this technique. It was necessary, h
