Analytical Solutions for TM Modes in Magneto-Optical Planar Waveguides

From Maxwell's equations, an analytical formulation is developed to calculate the propagation characteristics and field profiles of transverse magnetic (TM) modes on magneto-optical (MO) planar waveguides. Results show nonreciprocal behavior in terms of both modal effective index and field profile analyses. The proposed model can be used as a reference to assess the nonreciprocal potentialities of such structures.
