Abstract :
Arbitrary discontinuities between two different slab guides are analyzed. To check the validity of their method, the authors consider a step discontinuity. The finite-element region is chosen to enclose the junction. After obtaining the coefficients, they calculate the tangential fields at the junction. The field distributions at the planes z=0- and z=0+ are shown. The agreement of the curves ensures the continuation of the fields, and confirms the validity of the method. A typical result for reflection and transmission coefficients is presented.<>
