Paper Abstract

The diffraction far-field of planar waveguide is investigated and then rationality of the Gaussian approximation for it is clarified based on the characteristic of its beam propagation factor. A new definition for divergence half-angle is presented according to the maximal matching efficiency method, furthermore, relationship between the maximal matching efficiency divergence half-angle and normalized frequency is given.
