Relaxation methods applied to engineering problems - Free transverse vibrations of membranes, with an application (by analogy) to two-dimensional oscillations in an electro-magnetic system

Abstract

Membranes whether uniform or non-uniform in density are easily treated by a technique similar to that of Part VII B , and with an accuracy more than sufficient for practical purposes. An equation of the same mathematical form governs certain practically-important types of high-frequency electromagnetic oscillation, and here the illustrative example treated has direct importance for design.
