Acoustic Scattering from Large Aspect Ratio Elastic Targets

摘要

This paper applies the spheroidal T-matrix approach of Dr. Roger H hackman described in his paper 'The Transition Matrix for Acoustic and Elastic Wave Scattering in Prolate Spheroidal Coordinates', Journal of the Acoustic Society of America, 75(1), PP. 35-45 to describe the scattering from large aspect ratio targets. Due to the limits of double precision arithmetic in the computation of the spheroidal wave functions, these methods are limited to frequencies below kL/2 = 30.
