Abstract

Using the method of continued boundary conditions the scalar problem of diffraction of the field produced by the point source on the screen of revolution with variable impedance is solved. We consider the impedance boundary conditions of two types, which in the case of zero impedance are reduced respectively to the Dirichlet or Neumann conditions. The paper discusses both stationary and non-stationary diffraction problems. Numerical results are obtained for the screens of parabolic and spherical shape.
