✦ Synopsis

dition. The reflection boundary condition (RBC) and the absorbing boundary condition (ABC) are examples of such velocity boundaries that have been investigated with the problem of synthesizing a rectangular deep null in the sidelobe region. The obtained results show that by using an RBC or ABC, and then carefully choosing V max , it is possible to arrive at a much better convergence performance, as compared with those of the traditional soft boundary condition and the velocity-clipping criterion that uses the value of V max equal to the maximum dimension of the problem. Thus, the importance of V max increases with the incorporation of these boundary-condition types.
