Nonlocal transformation optics
Giuseppe Castaldi, Vincenzo Galdi, Andrea Alu' +1
We show that the powerful framework of transformation optics may be exploited for engineering the nonlocal response of artificial electromagnetic materials. Relying on the form-inv…
Experimental Verification of 3D Plasmonic Cloaking in Free-Space
David Rainwater, Aaron Kerkhoff, Kevin Melin +3
We report the experimental verification of metamaterial cloaking for a 3D object in free space. We apply the plasmonic cloaking technique, based on scattering cancellation, to supp…
Electromagnetic tunneling of obliquely-incident waves through a single-negative slab paired with a double-positive uniaxial slab
Giuseppe Castaldi, Vincenzo Galdi, Andrea Alu' +1
We show that, under appropriate oblique-incidence and polarization conditions, the inherent opaqueness of a homogeneous, isotropic single-negative slab may be perfectly compensated…
