Novel wave effects on anisotropic and ferrite planar slab waveguides in connection with singularity theory

The characteristic interactions of discrete modes supported by planar isotropic and anisotropic dielectric and ferrite slab waveguides are analyzed using singularity and critical point theory, leading to a rigorous and complete explanation of all modal interactions. For an anisotropic planar waveguide having an arbitrarily-orientated optical axis, it is… (More)
