A General Class of Metamaterial Transformation Slabs
Ilaria Gallina, Giuseppe Castaldi, Vincenzo Galdi +2
In this paper, we apply transformation-based optics to the derivation of a general class of transparent metamaterial slabs. By means of analytical and numerical full-wave studies,…
Cloak/anti-cloak interactions
Giuseppe Castaldi, Ilaria Gallina, Vincenzo Galdi +2
Coordinate-transformation cloaking is based on the design of a metamaterial shell made of an anisotropic, spatially inhomogeneous "transformation medium" that allows rerouting the…
Nonlinear Control of Tunneling Through an Epsilon-Near-Zero Channel
David A. Powell, Andrea Alu, Brian Edwards +3
The epsilon-near-zero (ENZ) tunneling phenomenon allows full transmission of waves through a narrow channel even in the presence of a strong geometric mismatch. Here we experimenta…
