We present experimental scattering data at microwave frequencies on a structured metamaterial
that exhibits a frequency band where the effective index of refraction (n) is negative. The …

We demonstrate a composite medium, based on a periodic array of interspaced conducting
nonmagnetic split ring resonators and continuous wires, that exhibits a frequency region in …

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 …

We analyze the reflection and transmission coefficients calculated from transfer matrix
simulations on finite lengths of electromagnetic metamaterials, to determine the effective …

We discuss the validity of standard retrieval methods that assign bulk electromagnetic
properties, such as the electric permittivity ε and the magnetic permeability μ, from calculations of …

Recently, artificially constructed metamaterials have become of considerable interest,
because these materials can exhibit electromagnetic characteristics unlike those of any …

A recently published theory has suggested that a cloak of invisibility is in principle possible,
at least over a narrow frequency band. We describe here the first practical realization of such …

… Smith and Ruopeng Liu, discusses the broad concepts of … Smith builds a general effective
medium theory for arti  cial … Smith describes a rapid design method for complicated …

We present the design for an absorbing metamaterial (MM) with near unity absorbance A (ω).
Our structure consists of two MM resonators that couple separately to electric and magnetic …

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 …
