Abstract. Diffraction of electromagnetic waves by a dielectric wedge is numerically analysed using the integral equation method. Amplitude and phase characteristics of the equivalent surface currents, the surface impedances and the scattered fields are analysed in detail for various incident angles of plane wave. The comparison of diffracted fields vs physical optics approximation is carried out.  

Keywords: electromagnetic plane wave, dielectric wedge, surface integral equations, surface  currents, surface impedance, diffraction field.
