Abstract
A new wiregrid modeling scheme is proposed for a curvature varying scatterer A 2-dimensional conducting elliptic cylinder is modelled by wires with the different size of radius considering the radius of curvature on the surface. The magnitude of the internal field in the conducting elliptic cylinder is used as an indicator to check the accuracy of solutions between two methods. Numerical results show that this new wiregrid model scheme can be reduced the number of wires and applied to enhance the accuracy of solutions for a curvature varying scatterer.
