Pairing an Epsilon-Negative Slab With a Mu-Negative Slab: Resonance, Tunneling and Transparency
Here, we analyze the transverse-magnetic (TM) wave interaction with a pair of slabs, one being an epsilonnegative (ENG) layer in which the real part of permittivity is assumed to be negative while its permeability has positive real part, and the other being a mu-negative (MNG) layer that has the real part of its permeability negative but its permittivity has positive real part. Although wave in...
متن کاملElectromagnetic Tunneling in Nonconjugated Epsilon-negative and Mu-negative Metamaterial Pair
In this paper, the tunneling phenomenon occurring at the interface with great impedance contrast is investigated by numerical calculation. It is found even in this case, perfect transmission can still be achieved theoretically when nonconjugated sub-wavelength epsilonnegative (ENG) and mu-negative (MNG) metamaterial pair is introduced. Moreover, the calculated electromagnetic field distribution...
متن کاملDiscrimination of Modes of Double- and Single-Negative Grounded Slab
In this paper, we investigate theoretically the waves propagation in a lossless double-negative grounded slab (DNG). This study is performed by the Transverse Resonance Method (TRM). The proper or improper nature of real and complex modes is observed. They are highly dependent on metamaterial parameters, i.e. ɛrnegative, μr-negative, or both. Numerical results provided that only the proper comp...
متن کاملNegative index short-slab pair and continuous wires metamaterials in the far infrared regime.
Using transmission and reflection measurements under normal incidence in one and three layers of a mum-scale metamaterial consisting of pairs of short-slabs and continuous wires, fabricated by a photolithography procedure, we demonstrate the occurrence of a negative refractive index regime in the far infrared range, ~2.4-3 THz. The negative index behavior in that system at ~2.4-3 THz is further...
متن کاملLimitations on subdiffraction imaging with a negative refractive index slab
A planar slab of material, for which both the permittivity and permeability have the values of 21, can bring not only the propagating fields associated with a source to a focus, but can also refocus the nonpropagating near fields, thereby achieving resolution beyond the diffraction limit. We study the sensitivity of this subwavelength focus to the slab material properties and periodicity, and n...
