Transient radiation from pistons

A classical problem. The Rayleigh integral easily gives the frequency-domain or time-domain result for the radiation from a piston. The result can, however, be written as a sum of a plane wave and an edge wave. A new method gives the edge wave as caused by directional edge sources [Svensson et al 2001].
