Non-Bragg gap solitons and absorption effects in Kerr-metamaterial periodic and Fibonacci heterostructures
A detailed study of non-Bragg gap solitons in one-dimensional Kerr-metamaterial periodic and Fibonacci heterostructures is performed. The transmission coefficient is numerically obtained by considering the loss effects in the metamaterial slabs. A switching from states of no transparency in the linear regime to high-transparency states in the nonlinear regime is observed for both zero-order and...
متن کاملEutectic epsilon-near-zero metamaterial terahertz waveguides.
We present and analyze the unique phenomena of enhanced THz transmission through a subwavelength LiF dielectric rod lattice embedded in an epsilon-near-zero KCl host. Our experimental results in combination with theoretical calculations show that subwavelength waveguiding of terahertz radiation is achieved within an alkali-halide eutectic metamaterial as result of the coupling of Mie-resonance ...
متن کاملMetamaterial Based Multiple Frequency Antenna
Antennas that are electrically small, efficient and have significant bandwidth would fill many needs of new generation communications systems if antenna engineers could reconcile these usually contradictory requirements. The introduction of the so-called metamaterials (MTMs), artificial materials which have engineered electromagnetic responses that are not readily available in nature, has provi...
متن کاملInvisible Hyperbolic Metamaterial Nanotube at Visible Frequency
Subwavelength-scale metal and dielectric nanostructures have served as important building blocks for electromagnetic metamaterials, providing unprecedented opportunities for manipulating the optical response of the matter. Recently, hyperbolic metamaterials have been drawing particular interest because of their unusual optical properties and functionalities, such as negative refraction and hype...
متن کاملFrequency Reconfigurable Epsilon Negative Metamaterial Antenna
Received Feb 15, 2017 Revised Apr 22, 2017 Accepted May 7, 2017 This paper proposes metamaterial (MTM) inspired frequency reconfigurable antenna based on thecircular electric field coupled (ELC) resonator. It is composed of circular shape ELC resonator with the radius size of 7 mm. By inserting two switches between the gaps at both side of the circular ELC resonator, it is possible to switch ON...
