Summary

Description
English: Waves incident on the front (top) or back (middle) of a partially absorbing medium will be partially transmitted and reflected. However, if counterpropagating and mutually coherent waves are simultaneously incident, the level of absorption can be enhanced by destructive interference of transmitted and reflected waves (bottom). Complete cancellation of these waves results in Coherent Perfect Absorption, where all incident wave energy is absorbed.

Coherent perfect absorption arises from destructive interference of transmitted and reflected waves, which traps wave energy within an absorber until it is absorbed.
