Abstract

An armor system includes an armor plate, and an appliqué affixed to an exterior of the armor plate, wherein the appliqué has a density increasing in a direction towards the armor plate and configured to minimize reflection of a blast wave from the armor plate. The coupling system comprises a binder material that surrounds filler particles configured to create an impedance gradient parallel to the impulse propagation direction.
