Unbounded spatial spectrum of propagating waves in a polaritonic wire medium
Unbounded spatial spectrum of propagating waves in a polaritonic wire medium
In this paper, we study a topological phase transition in a wire medium operating at infrared frequencies. This transition occurs in the reciprocal space between the indefinite (open-surface) regime of the metamaterial and its dielectric (closed-surface) regime. Due to the spatial dispersion inherent to a wire medium, a hybrid regime …
