On a Fredholm Equation in Diffraction Theory (Classic Reprint)
Excerpt from On a Fredholm Equation in Diffraction Theory We consider here the problem of the diffraction of a plane scalar wave normally incident on a plane screen with a circular aperture. Let u be the solution of Au K2u O, which represents the diffracted wave, and let p, 9 be polar coordinates on the screen such that p 0 represents the center of the aperture. We assume that on the screen u 0. Let the radius of the aperture be a and let Q (p) be the value of u in the aperture, 0 5 p 5 a. Bomkamp  using the Levine and Schwinger  variational method, derived the following result. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
