Diffraction of a plane nonuniform wave on the halfplane
Abstract
The classical problem of plane uniform waves solved by Sommerfeld is reexamined, with attention given to propagation of nonuniform waves appearing in response to total internal reflection, refraction on an absorbing wedge, and refraction in an absorbing medium. Vectors of the magnetic and electric fields of the diffracted wave are defined and the asymptotic behavior of the solution is analyzed. Data calculated for the field near the plane are compared, for different levels of attenuation, with calculated results for diffraction of a uniform wave. Use of the polarization dependence of the direction of the Poynting vector of a plane nonuniform wave to analyze the spatial spectrum (distributed over states of polarization) of the beam is discussed.
