N2 - Time domain computations of electromagnetic wave scattering solving the associated hyberbolic differential equations has been shown to be an effective method of studying wave scattering. The finite difference and finite element methods have the problems of conforming to the scattering boundaries and the finite element method requires extra memories to store the coordinate locations of each node. Recently, the conforming boundary element method has been investigated, where the irregular elements are only limited to the elements, which cross the boundaries of the scatterer. With this approach, we can apply the finite element method without excessive demand on memories. We show how scattering by a three dimensional target, such as a finite cylinder with fins, can be calculated. The surface current densities on the scatterer are computed.
