Abstract
We present a family of bidirectional beam propagation methods based on the application of Fade approximants to the square-root expressions appearing i n the transition operator. We show that the numerical instability associate d with the use of real Pade primes can be removed by using branch-cut rotat ion of the square-root operator.
