Title: "Gravitational Waves and Electrodynamic Phenomena induced by Curvature"

Non-minimal coupling of gravitational and electromagnetic fields is considered on the examples of exactly solvable models of evolution of relativistic electrodynamic systems in a pp-wave gravitational background. Birefringence, the Cherenkov effect and optical activity induced by curvature, singular behaviour and anomalies in electric and magnetic fields, spontaneous polarization-magnetization of pyro-piezo-active media, non-linearity induced by curvature, and parametric phenomena are discussed.
