In this work we implement theoretical proposal of Smolyaninov and Narimanov (Phys. Rev. Lett. 105, 067402 (2010)) who demonstrated that extraordinary light waves in hyperbolic metamaterials may exhibit “two times” physics behavior. This behavior is observed via experimental study of nonlinear optics of iron/cobalt ferrofluid-based hyperbolic metamaterials, which shows considerable similarities with gravitation theory. We will present high-resolution images of self-focusing effect in this metamaterial, which were obtained as a function of light intensity and varying incidence angle with respect to the optical axis of the metamaterial.
In this work we implement theoretical proposal of Smolyaninov and Narimanov (Phys. Rev. Lett. 105, 067402 (2010)) who demonstrated that extraordinary light waves in hyperbolic metamaterials exhibit “two times” physics behavior. This behavior is observed via experimental study of gravity-like nonlinear optics of iron/cobalt-based ferrofluid hyperbolic metamaterials. In addition to conventional temporal coordinate, the spatial coordinate oriented along the optical axis of the metamaterial also exhibits timelike character, which leads to very unusual “two times” physics behavior in these systems.
