Abstract :
By utilizing an analytical effective medium and an exact numerical approaches we design a magnetoplasmonic hyperbolic metamaterial with broadband nonreciprocal response. It is shown that such metamaterial, with reduced spatial symmetry and the time-reversal symmetry broken by magnetization, exhibits multiple nonreciprocal hyperbolic regimes. Magnetization induced one-way topological phase transitions between elliptical and hyperbolic regimes are demonstrated.
