Polarization Inversion with $\mathcal{P}\cdot \mathcal{T}\cdot \mathcal{D}$ Symmetric Scatterers

Roee Geva, Mário G. Silveirinha, Raphael Kastner

We demonstrate, both theoretically and experimentally, that arbitrary scatterers preserving parity-time-duality ($\mathcal{P}\cdot \mathcal{T}\cdot \mathcal{D}$) symmetry inherently…
