摘要

A method for deriving the partial differential operator factorizations of the scalar wave equation in the time-domain were derived by Engquist and Majda (1977). An alternative way to derive these equations in the frequency-domain is presented. It is shown that the limitation and accuracy of the resulting one-way wave equations may be easier to observe from this derivation. The possibility of the similar finite-difference method based on the one-way wave equations derived by the operator factorization is also discussed.
