Abstract

Deformations of sandwich gravitational waves are considered. Squeezing a wave with pure displacement (DM) parameters to an impulsive wave, the DM property is lost, leaving us with the velocity effect (VM). For each fixed value of the deformation parameter $p$ , DM can be restored by further increasing the amplitude which however diverge when $p\to\infty$ , and no impulsive wave is obtained.
