Transition matrix in acoustic scattering by a strip

Abstract
The transition matrix describing the scalar scattering by a strip has been obtained using a boundary‐integral‐equation technique. It avoids the procedure of the extended boundary condition, taking the strip as the limit of an elliptic cylinder. Our final results confirm the known results obtained from the extended‐boundary‐condition technique. The method presented in this paper seems to be very attractive to similar problems in elastodynamic scattering.
