In the last few years, a rapid development has been achieved in a subject area, so called
optical transformation, which is based on the property of metric invariance in Maxwell's …

The coordinate transformation by using form-invariant transformations of Maxwell equations
has led to an approach for designing devices with anisotropic metamaterial. In this paper …

A one-directional invisibility cloak is presented in this letter. Perfect invisibility can be
achieved for TM waves along certain directions. The parameters are just homogeneously …

We apply coordinate transformations in the design of waveguides with bent geometry to
reduce reflection at the incident port. It was found that in the case of metallic waveguides, by …

A derivation of metamaterial blueprints for the reflectionless (perfectly matched) guiding of
electromagnetic waves through waveguide bends is performed. The sensitivity of the …

Arbitrary N-sided regular polygonal cylindrical cloaks are proposed and designed based on
the coordinate transformation theory. First, the general expressions of constitutive tensors of …

We introduce a new approach which enables a waveguide to support propagation of
electromagnetic waves below the cutoff frequency, as well as which avoids undesirable …

We investigate the design of metamaterial blueprints for impedance-matched (reflectionless)
absorbers over nonplanar surfaces in connection with optical pseudo black holes. The …

We present spatial-coordinate transformation techniques to control the propagation of
electromagnetic fields in several surprising and useful applications. The implementation of …

We investigate the electromagnetic properties of three-dimensional (3D) arbitrarily-shaped
invisible cloaks based on the analytical field transformation theory instead of the …
