A uniform version of the potential function of the Maggi-Rubinowicz boundary diffraction wave theory is obtained by using the large argument expansion of the Fresnel integral. The derived function is obtained for the problem of diffraction of plane waves by a circular edge. The results are plotted n

✦ Synopsis
A novel potential function of the boundary diffraction wave theory is obtained for the impedance surfaces by the asymptotic reduction of the modified theory of physical integrals. The function is expressed in terms of the direction vectors of the incident and scattered rays. The application of the method is performed on the problem of diffraction of plane waves by an impedance half plane for oblique incidence.

The method of continued boundary conditions is extended to the problems of electromagnetic waves scattering by bodies with impedance boundary. The boundary problem is reduced to Fredholm integral equation of the second kind with a smooth kernel. The results of the calculations showing efficiency of
We discuss two different representations of a single imperfect trap in one dimension, a g-function potential in a Schr6dinger-like reaction-diffusion equation, and the classical radiation boundary condition description. In the context of self-segregation in trapping problems, we show explicitly the
This paper concerns the least-energy solutions to a semilinear elliptic equation. The role of geometry of the boundary is studied when a parameter in the boundary condition tends to a critical index as well as to inlinity. . 1995 Acadernic Press. Inc.
