A transverse displacement at the junction of two planar dielectric waveguides

The guided-wave transmission and reflection coefficients, the pattern, and the energy of the radiated field are calculated as functions of the value of the displacement at the junction of two single-mode waveguides for various values of the permittivity of waveguiding layers. It is shown that the correction to the wave transmission coefficient calculated at the first and second iteration steps increases while the permittivity grows, and the way this correction increases is demonstrated.
