Complex and interesting electromagnetic behavior can be found in spaces with non-flat topology. When considering the properties of an electromagnetic medium under an arbitrary coordinate transformation an alternative interpretation presents itself. The transformed material property tensors may be interpreted as a different set of material properties in a flat, Cartesian space. We describe the calculation of these material properties for coordinate transformations that describe spaces with…

This article writes Maxwell's equations in the most general form and derives a coordinate-free form for the eikonal equation and hence the Hamiltonian of a general purpose medium, which works for both orthogonal and non-orthogonal coordinate systems.

Electromagnetic cloaking in convex and concave media with surface modelled as a parameterised function.

An algorithm is proposed using a coordinate transformation and a piecewise function for the purpose of designing a three dimensional cloak having an arbitrary geometry which could be convex or non-convex in nature.

Medium parameters and electromagnetic characteristics of arbitrary polygon cloaks

An important class of two-dimensional (2D) cloaks with polygonal geometries is presented. Explicit expressions of complex medium parameters are derived based on the direct transformation in the

A classical method based on analytical results and a transformation optics method using an arbitrary piecewise continuous transformation function are applied to design a 1D electromagnetic transparent wall, whose presence does not disturb the field distribution in the ambient environment.

Analysis of the equivalent scattering properties of a target embedded in transformation media

Transformation electromagnetics reveals that electromagnetic fields can be manipulated in almost any desired manner using specially tailored transformation media. The equivalent scattering property

Optic axes of general anisotropic media: a geometric algebra perspective

For simple electric (magnetic) anisotropy, a single mapping between the permittivity (permeability) value and the direction of space describes the medium properties. The wellknown classification of

The transformation media concept based on the form-invariant Maxwell's equations under coordinate transformations has opened up new possibilities of manipulating electromagnetic (EM) fields. In this



Refraction and geometry in Maxwell's equations

Computational studies of Maxwell's equations in complex geometries encountered in photonic band structure calculations run into difficulties when several length scales occur, such as the wavelength

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

Controlling Electromagnetic Fields

This work shows how electromagnetic fields can be redirected at will and proposes a design strategy that has relevance to exotic lens design and to the cloaking of objects from electromagnetic fields.

This experimental verification of negative refraction of electromagnetic waves in a two-dimensional dielectric photonic crystal that has a periodically modulated positive permittivity and a permeability of unity is demonstrated.

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

Here it is seen how a proper design of these lossless metamaterial covers near their plasma resonance may induce a dramatic drop in the scattering cross section, making these objects nearly "invisible" or "transparent" to an outside observer--a phenomenon with obvious applications for low-observability and noninvasive probe design.

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.

Regions of anomalous localized resonance, such as occurring near superlenses, are shown to lead to cloaking effects. This occurs when the resonant field generated by a polarizable line or point
