Nonreciprocity and one-way topological transitions in hyperbolic metamaterials
Control of the electromagnetic waves in nano-scale structured materials is crucial to the development of next generation photonic circuits and devices. In this context, hyperbolic metamaterials, where elliptical isofrequency surfaces are morphed into surfaces with exoti...

description |
Control of the electromagnetic waves in nano-scale structured materials is
crucial to the development of next generation photonic circuits and devices. In this
context, hyperbolic metamaterials, where elliptical isofrequency surfaces are morphed into
surfaces with exotic hyperbolic topologies when the structure parameters are tuned, have
shown unprecedented control over light propagation and interaction. Here we show that such
topological transitions can be even more unusual when the hyperbolic metamaterial is endowed with
nonreciprocity. Judicious design of metamaterials with reduced spatial symmetries, together
with the breaking of time-reversal symmetry through magnetization, is shown to result in
nonreciprocal dispersion and one-way topological phase transitions in hyperbolic
metamaterials. |
