A zero index metamaterial (ZIM) can be utilized to block wave (super-reflection) or conceal
objects completely (cloaking). The “super-reflection” device can be realized by a Mu zero
(Epsilon zero) metamaterial with a perfect electric (magnetic) conductor inclusion of ...

Abstract We theoretically investigate microwave transmission through a zero-index
metamaterial loaded with dielectric defects. The metamaterial is impedance matched to free
space, with the permittivity and permeability tending towards zero over a given frequency ...

In this work, we investigate wave transmission through an epsilon-near-zero metamaterial
waveguide embedded with defects. We show that by adjusting the geometric sizes and
material properties of the defects, total reflection, and even transmission can be obtained, ...

A zero-refractive-index metamaterial is one in which waves do not experience any spatial
phase change, and such a peculiar material has many interesting wave-manipulating
properties 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. These materials can in principle be realized using ...

Abstract Silveirinha and Engheta have recently proposed that electromagnetic waves can
tunnel through a material with an electric permittivity (ϵ) near zero (ENZ). An ENZ material of
arbitrary geometry can thus serve as a perfect coupler between incoming and outgoing ...

We study metamaterials with an anisotropicpermittivitytensor in which one component is
near zero. We find that such an anisotropicmetamaterial can be used to control wave
propagation and construct almost perfect bending waveguides with a high transmission ...

Using some special properties of a permeability-near-zero material, the radiation of a line
current is greatly enhanced by choosing appropriately the dimension of a dielectric domain
in which the source lies and that of a permeability-near-zero shell. The radiation of the ...

Abstract In this work, we investigate the detailed theory of the supercoupling, anomalous
tunneling effect, and field confinement originally identified by Silveirinha and Engheta [Phys.
Rev. Lett. 97, 157403 (2006)], where we demonstrated the possibility of using materials ...

Abstract In this work, we study the electrodynamics of metamaterials that consist of resonant
non-magnetic inclusions embedded in an epsilon-near-zero (ENZ) host medium. It is shown
that the inclusions can be designed in such a way that both the effective permittivity and ...

Abstract Utilizing a microwave setup, we experimentally verify our recently developed theory
of energy squeezing and tunneling [Phys. Rev. Lett. 97, 157403 (2006)] through an
ultranarrow waveguide channel that mimics zero-permittivity properties. Exploiting the ...
