Experimental Verification of Ill-defined Topologies and Energy Sinks in Electromagnetic Continua
David E. Fernandes, Ricardo A. M. Pereira, Sylvain Lannebère +2
In this article, it is experimentally verified that nonreciprocal photonic systems with a continuous translation symmetry may have an ill-defined topology. The topological classifi…

Role of Time-Reversal Symmetry in the Dynamical Response of "One-Way" Nonlinear Devices
David E. Fernandes, Mário G. Silveirinha
We study the role of time-reversal symmetry on the dynamical response of nonlinear optical systems that behave as unidirectional ("one-way") devices. It is shown that lossless nonl…
