Optical concentrator from a hyperbolic liquid crystal metamaterial
Frankbelson dos S. Azevedo, David Figueiredo, Fernando Moraes +2
We examine the optical properties of two different configurations of a cylindrical device made from a hyperbolic metamaterial with optical axis defined by circular and radial direc…
Cosmology in the laboratory: an analogy between hyperbolic metamaterials and the Milne universe
David Figueiredo, Fernando Moraes, Sébastien Fumeron +1
This article shows that the compactified Milne universe geometry, a toy model for the big crunch/big bang transition, can be realized in hyperbolic metamaterials, a new class of na…
Modeling Kleinian cosmology with electronic metamaterials
David Figueiredo, Felipe Azevedo Gomes, Sébastien Fumeron +2
This paper deals with the propagation of Klein-Gordon particles in flat background spacetime exhibiting discontinuous metric changes from a Lorentzian signature (-,+,+,+) to a Klei…
