Electrodynamics of Accelerated Space-Time Engineered-Modulation Metamaterials

We present the first systematic study of Accelerated Space-Time Engineered-Modulation (ASTEM) metamaterials, or ASTEMs. Leveraging the tools of general relativity, we establish their electrodynamic principles and describe related fundamental phenomena. We show that an electromagnetic beam propagating in an ASTEM is bent in its course, which reveals that such a medium curves space-time for light, similarly to gravitation, and further demonstrate black hole and white hole gravity analogs. This paper extends the fields of uniform-velocity metamaterials and paves the way to a host of related novel physics and applications.
