Abstract :
The authors report the application of curved parametric triangular and quadrilateral edge elements as basis functions in the moment method (MM) solution of the electric field integral equation (EFIE). In this way, an arbitrarily shaped surface can be modeled more accurately than with conventional planar patches. Consequently, higher accuracy in the numerical solution can be obtained, as demonstrated by numerical examples.<>
