Abstract :
We examine the performance of absorbing boundary conditions (ABCs) as well as material absorbers applied to a circular boundary. The absorption of cylindrical wave functions is examined sat the interface of the various truncation schemes, and expressions for the modal reflection coefficient are obtained. The results are then used to solve for the scattered field due to a perfect electrical conducting cylinder surrounded by a given absorbing termination.
