Electromagnetic shock waves undergo measurable Faraday rotation when interacting with gravitational waves.

The approach is grounded in the principles of general relativity.

Abstract

A method is given which renders indirect detection of strong gravitational waves possible. This is based on the reflection (collision) of a linearly polarized electromagnetic shock wave from (with) a cross polarized impulsive and shock gravitational waves in accordance with the general theory of relativity. This highly non-linear process induces a detectable Faraday rotation in the polarization vector of the electromagnetic field.
