Publisher's Synopsis
Excerpt from Equivalence Relations in Diffraction Theory
One example of the utility of equivalence relations between different problems is afforded by Kel vin's well-known method of imsges where the original boundary-value problem is transformed into one for a larger domain for which a solution is generally available by inspection. Babinet's principle D] in dif fraction theory is a further example of the utility of equivalence relationships betweeen different boundary-value problems. It is of interest to note that the process used in the present paper may be applied to deduce Babinet's principle.
