Abstract
The application of geometrical diffraction theories to dielectric obje cts requires usually an extensive mathematical formalism. In this pape r, a simple adaptation of the Uniform Asymptotic Theory to thick arbit rary shaped dielectric slabs with small refractive index and negligibl e attenuation is presented. Calculated nearfields are compared with me asurements by means of 3 cm microwaves. The polarization dependence of the given adaptation is discussed.
