Acoustic scattering by a soft elliptic disk
Författare
Summary, in English
Scattering from an acoustically soft elliptic disk is treated by means of the null field approach. It is shown that in the disk limit of a general ellipsoid the relevant matrix elements have a well-defined limit, and that the formulation is attractive for numerical calculations. In a separate section the low frequency expressions of the total cross section and the far field amplitude are also derived. The paper is closed by a presentation of a series of numerical calculations.
