Abstract
The diffraction of plane waves by an elliptic cylinder is studied by employing expansions in Mathieu functions. Both Dirichlet and Neumann boundary conditions are investigated. The scattered intensity in the far field and total scattered power are derived and their long‐wave (Rayleigh) scattering approximations studied. Numerical results are presented for both the long‐wave and medium‐wave regions.Keywords
