We present an electron energy loss study using energy filtered TEM of spatially resolved surface plasmon excitations on a silver nanorod of aspect ratio 14.2 resting on a 30 nm thick silicon nitride m...
Electromagnetic tunneling of obliquely-incident waves through a single-negative slab paired with a double-positive uniaxial slab
single-negative slab double-positive uniaxial slab
2011/9/2
We show that, under appropriate oblique-incidence and polarization conditions, the inherent opaqueness of a homogeneous, isotropic single-negative slab may be perfectly compensated (in the ideal lossl...
