THE INTERACTION OF WAVES WITH A ROW OF CIRCULAR-CYLINDERS

The two-dimensional acoustics problem of the scattering of an obliquel y incident plane wave by a row of equally-spaced circular cylinders is solved using multipole expansions. The method is superior to existing techniques available for this problem as it allows the far-field beha viour of the solution to be evaluated in a straightforward manner, and extensive results for the reflection and transmission coefficients ar e given. The problem described above has a direct analogue in the theo ry of water waves and this is also discussed.
