Abstract:
The scattering problem for an inhomogeneous two-dimensional biisotropic cylinder is solved in the frequency-domain by means of a hybrid method, in which finite difference equations in the interior region are combined with a mesh truncation in terms of a boundary integral equation. Numerical results for the bistatic echo widths are presented and compared with a reference solutions in the circular cylinder cases and it is found that the method yields more accurate results than what can be achieved with a local absorbing boundary condition.
