Paper Abstract

The present work offers a new method for the direct measurement of the propagation constants difference (Delta) (beta) of orthogonal modes (mode beat) of the same order in planar waveguides. The work also presents the method to determine the difference of propagation constants (mode beat) for different refractive indexes of the cover.
