Abstract

A ray-theoretic analysis of the problem of discontinuity in a linear guide is presented. The fields in the guides are expressed as superposition of plane wave components determined by subjecting the fields to the process of Fourier transformation. The reflected fields are finally synthesized by modifying these plane wave components by the corresponding Fresnel coefficients at the plane of discontinuity. The results obtained are compared with those obtained by other methods.
