Double-knife edge problems with elastic/plastic type screens (Q1175042)

This work gives a mathematical model for an acoustically penetrable or electromagnetically dielectric half-plane. An approximate boundary condition is used that depends on the thickness of, and the material constants for, the half-plane. A solution is obtained, by using the approximate boundary condition, for the problem of a line source field diffracted by a penetrable/dielectric half-plane. The asymmetrie of the approximate boundary condition results in a matrix Wiener-Hopf problem, which is solved explicitly.
