Abstract

A comparison of results for an analogous scattering problem is made for the interactive scattering of a double sphere in both acoustics and electromagnetic scattering. For initial testing purposes, the problem is simplified to that of two identical spheres with the same size and physical properties. The acoustical scatterer is modeled to match optical characteristics of the already studied optical scattering problem [G. W. Kattawar and C. E. Dean, Opt. Lett. 8, 48-50 (1983).]. Particular study is made of situations that lead to large side scattering responses due to resonance phenomena. The model for the acoustical scattering problem was discussed in a previous Acoustical Society of America meeting [C. E. Dean and J. P. Braselton, J. Acoust. Soc. Am. 139, 1121 (2016)].
