Computation of the scattering from inhomogeneous objects with a discrete rotational symmetry and a nonsymmetric part.

Computation of the scattering from inhomogeneous objects with a discrete rotational symmetry and a nonsymmetric part.

Using a specific solver for circulant matrices can reduce the cost of computing the scattering from a discrete rotational symmetric object by up to several orders of magnitude. A solver is developed for symmetric objects with a nonsymmetrical part (such as an antenna on a body of revolution). This s...
