Switching a plasma-like metamaterial via embedded resonant atoms exhibiting electromagnetically induced transparency
Sangeeta Chakrabarti, S. Anantha Ramakrishna, Harshawardhan Wanare
We theoretically demonstrate control of the plasma-like effective response of a metamaterial composed of aligned metallic nanorods when the electric field of the incident radiation…

Near Field Lenses in Two Dimensions
J. B. Pendry, S. Anantha Ramakrishna
It has been shown that a slab of materials with refractive index = -1 behaves like a perfect lens focussing all light to an exact electromagnetic copy of an object. The original le…

Propagating and evanescent waves in absorbing media
S. Anantha Ramakrishna, A. D. Armour
We compare the behavior of propagating and evanescent light waves in absorbing media with that of electrons in the presence of inelastic scattering. The imaginary part of the diele…
