Controlling Electromagnetic Fields

  title={Controlling Electromagnetic Fields},
  author={John Brian Pendry and David Schurig and D. Robert Smith},
  pages={1780 - 1782}
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 displacement field D, magnetic induction field B, and Poynting vector B—are all displaced in a consistent manner. A simple illustration is given of the cloaking of a proscribed volume of space to exclude completely all electromagnetic fields. Our work has relevance to exotic lens design and to the cloaking of objects…

A method for arbitrarily controlling the phase progression and power flow of electromagnetic fields within a region of space is introduced. Specifically, the method describes how to design a 2D

Control of the Electromagnetic Fields by Metamaterials

Metamaterials are engineered composites [1-3]. Much of the effort in the electrical engineering, material science, physics, and optics communities emphasized constructing efficient metamaterials and

Transformation media that rotate electromagnetic fields

The authors suggest a way to manipulate electromagnetic waves by introducing a rotation mapping of coordinates that can be realized by a specific transformation of the permittivity and permeability

General relativity in electrical engineering

In electrical engineering metamaterials have been developed that offer unprecedented control over electromagnetic fields. Here, we show that general relativity provides the theoretical tools for

Cloaking of objects from electromagnetic fields by inverse design of scattering optical elements.

An alternative approach toward cloaking in the near infrared wavelength region is presented by using inverse designed scattering optical elements, showing that it is possible to isolate a 1 mum2 area by guiding the a plane incident wave of the wavelength 1550nm around it.

We present a simple design of electromagnetic shields for both field expelling and field confinement. Motivated by the concept of neutral inclusions in the theory of composites, we introduce two

Scattering free graded index profiles and the control of electromagnetic fields

We present a general methodology to arbitrarily manipulate the amplitude and phase of an electromagnetic wave propagating in a two-dimensional medium, without introducing any scattering. This leads

Recent advances in metamaterials research are described and the potential that these materials may hold for realizing new and seemingly exotic electromagnetic phenomena is discussed.

Magnetic Response of Metamaterials at 100 Terahertz

The measured optical spectra of the nanofabricated gold structures come very close to the theoretical expectations and additional numerical simulations show that the structures exhibit a frequency range with negative permeability for a beam configuration in which the magnetic field couples to the LC resonance.

Free-space microwave focusing by a negative-index gradient lens

Metamaterial structures designed to have simultaneously negative permittivity and permeability are known as left-handed materials. Their complexity and our understanding of their properties have

Terahertz Magnetic Response from Artificial Materials

It is shown that magnetic response at terahertz frequencies can be achieved in a planar structure composed of nonmagnetic conductive resonant elements and suggested that artificial magnetic structures, or hybrid structures that combine natural and artificial magnetic materials, can play a key role in teraHertz devices.

Electromagnetic parameter retrieval from inhomogeneous metamaterials.

It is shown here that a modification of the standard S-parameter retrieval procedure yields physically reasonable values for the retrieved electromagnetic parameters, even when there is significant inhomogeneity within the unit cell of the structure.

Experimental Verification of a Negative Index of Refraction

These experiments directly confirm the predictions of Maxwell's equations that n is given by the negative square root ofɛ·μ for the frequencies where both the permittivity and the permeability are negative.
