Abstract
We present a general technique for constructing nonlocal transparent b oundary conditions for one-dimensional Schrodinger-type equations. Our method supplies boundary conditions for the theta-family of implicit one-step discretizations of Schrodinger's equation in time. The use of Mikusinski's operator approach in time avoids direct and inverse tran sforms between time and frequency domains and thus implements the boun dary conditions in a direct manner.
