Synopsis

Excerpt from Notes on Diffraction: By a Circular Disk

Another is based on the wiener-hopf method of solving integral equations with kernels having special properties. It was recently first applied in diffraction by Schwinger to the problem of the bifurcated wave guidez. It is known that any wave problem may be formulated by a partial differential equation the wave equation with appropriate boundary conditions, or by an integral equation comprising the boundary conditions. The latter can.be obtained by Green's function techniques. If, and.only if, the kernel is a function of the difference of its arguments can.this method be employed. This limits the variety of scatterers. Among other problems to which the method has been successfully applied are the radia tion from a semi - infinite cylinder}, and the diffraction from two and from an infinite set of parallel halfeplanesu.

Product Description

Excerpt from Notes on Diffraction: By a Circular Disk This report investigates diffraction of a plane sound wave from a rigid circular disk of zero thickness. A recently published exact theory is extended to compute and discuss values for the diffracted field both at the disk and at large distances from it. The Kirchhoff solution - an approximation designed for the case of very short wave length - is compared to the exact solution and it is found to be more powerful than might heretofore have been supposed. The reasons for this are discussed in some detail. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
