The conventional time domain finite difference (TDFD) method uses right rectangular meshes in space. The result is that curved object surfaces are approximated by steps. This paper considers finite difference meshes, which are not restricted to any shape, thus capable of conforming to the object surfaces. Other advantages of this type of meshes include the easier handling of the approximate radiation conditions.
