Abstract:

A method already developed for the diffraction of scalar waves by a circular disc is generalised so as to be applicable to the diffraction of an electromagnetic wave. The generalisation leads, in a straightforward manner, to an asymptotic development of the current density on the disc at high frequencies. The principal complication which arises is in solving three simultaneous linear equations for three constants which occur in the method of solution. Detailed calculations are given for a normally incident plane wave. Author
