Controlling Electromagnetic Fields
Using the freedom of design that metamaterials provide, we show how electromagnetic fields can be redirected at will and propose a design strategy. The conserved fields—electric...

With a conventional lens sharpness of the image is always limited by the wavelength of light. An unconventional alternative to a lens, a slab of negative refractive index materi...
Magnetism from conductors and enhanced nonlinear phenomena
We show that microstructures built from nonmagnetic conducting sheets exhibit an effective magnetic permeability /spl mu//sub eff/, which can be tuned to values not accessible i...
Extremely Low Frequency Plasmons in Metallic Mesostructures
The plasmon is a well established collective excitation of metals in the visible and near UV, but at much lower frequencies dissipation destroys all trace of the plasmon and typ...
Low frequency plasmons in thin-wire structures
A photonic structure consisting of an extended 3D network of thin wires is shown to behave like a low density plasma of very heavy charged particles with a plasma frequency in t...
Collective Theory for Surface Enhanced Raman Scattering
We present an implementation of Maxwell's equations on adaptive meshes in order to study interaction of light with metal surfaces. For the first time it is possible to handle su...
Calculation of photon dispersion relations
The current generation of photon scattering experiments requires a fast, accurate, general technique for calculation of transmission coefficients and of photonic band structure....
A program for calculating photonic band structures and transmission coefficients of complex structures
We present here a program which will calculate either the photonic band structure or the transmission and reflection coefficients of photons incident on some complex metallic or...
Calculating photonic band structure
Photonic materials structured on the scale of the wavelength of light have become the subject of an active field of research fed by the hope of creating novel properties. Theory...
Metamaterials and Negative Refractive Index
Recently, artificially constructed metamaterials have become of considerable interest, because these materials can exhibit electromagnetic characteristics unlike those of any co...
Terahertz Magnetic Response from Artificial Materials
We show that magnetic response at terahertz frequencies can be achieved in a planar structure composed of nonmagnetic conductive resonant elements. The effect is realized over a...
Refraction and geometry in Maxwell's equations
Abstract Computational studies of Maxwell's equations in complex geometries encountered in photonic band structure calculations run into difficulties when several length scales ...
