Publisher's Synopsis
Excerpt from Multiple Diffraction by an Aperture in a Hard Screen
The present authors have previously presented two different methods for calculating the field diffracted when a wave hits an aperture in a thin Both methods were applied to soft screens, i.e. Screens on which the wave function vanishes. Some results were also given in [l] for hard screens on which the normal derivative of the wave function vanishes, but interaction between various parts of the edge of the screen. Was not taken into account. In the present article these two methods are extended to yield more complete results for hard screens, in that interaction is taken into account.
