Scattering theory deals with the interactions of waves with obstacles in their path, and low frequency scattering occurs when the obstacles involved are very small. This book gives an overview of the subject for graduates and researchers, for the first time unifying the theories covering acoustic, electromagnetic and elastic waves.second transmission condition. It is clear that when *5 vanishes the problem becomes exactly the same as (4.20) in the lossless case. Once Al+ ... The low frequency expansion of aa may be obtained from (2.40) as x / Vw~-m(r), Vw~*(r) rfy(r) (4.28) v- Since for plane wave incidence Alu = l. this may be rewritten as ~Al: ( , , *)aquot; ^Janbsp;...
