A new wiregrid modelling scheme for a curvature varying scatterer is propos
ed. A conducting elliptic cylinder is modelled by mires with radii of diffe
rent sizes depending on the radius of curvature on the surface. The size of
each wire is generated from the model equation suggested in the study. Num
erical results show that this new wiregrid model can be applied to enhance
the accuracy of solutions for a curvature varying scatterer.
