Abstract
In this study a modified elastic wave equation is described which simultaneously permits both upgoing and downgoing propagation. This equation can be expressed as a nonreflecting elastic wave equation Which gives reduced reflection coefficients for transrnission across material boundaries. For horrogeneous region, it becomes the full elastic wave equation.
