This paper describes the design and simulation of the new Ɛ negative metamaterial unit cell structure and then the unit cells are combined to form 3D array which use as metamaterial cover with a single microstrip patch antenna. The new Ɛ negative metamaterial is based on the ELC resonator structure, which is used for obtaining the negative value of permittivity and positive value of permeabilit...

A metamaterial integration for fiber optics, leading to a dual effect of surface plasmon and classical waveguiding, is presented along with experimental potentiality. We theoretically propose a metamaterial fiber in which, depending on the wavelength (from ultraviolet to infrared) and the particular metamaterial composition, one can transmit information through surface plasmon mediated or class...

To obtain the eigenmodes of the electromagnetic field at a periodically corrugated metamaterial we consider a theory of spoof plasmons propagating on metamaterial perforated with planar periodic grooves. We present the rigorous modeling and analysis of surface waves at the boundary of the corrugated metamaterial structure. Particularly, we pay special attention to the ways of controlling the pr...

Simulated and experimental investigations have been carried out on annular ring antenna designed on metamaterial substrate. Different configurations of Sshaped metal structure are designed on RT-Duroid substrate to achieve metamaterial behavior at the frequency of 10.5 GHz. Annular ring antenna is designed for TM31 mode on the metamaterial configurations. The antenna provides a huge size reduct...

Metamaterials, materials that are constructed with arrays of small elements have significant potential to provide material properties that are useful for electromagnetic applications but are not found in nature. Slight changes to a repeated unit cell can be used to tune the effective bulk material properties of a metamaterial, replacing the need to discover suitable materials for an application...

Recent experiments have demonstrated that the metamaterial approach is capable of drastic increase of the critical temperature T c of epsilon near zero (ENZ) metamaterial superconductors. For example, tripling of the critical temperature has been observed in Al-Al 2 O 3 ENZ core-shell metamaterials. Here, we perform theoretical modelling of T c increase in metamaterial superconductors based on ...

Recent experiments have shown the viability of the metamaterial approach to dielectric response engineering for enhancing the transition temperature, Tc, of a superconductor. In this report, we demonstrate the use of Al2O3-coated aluminium nanoparticles to form the recently proposed epsilon near zero (ENZ) core-shell metamaterial superconductor with a Tc that is three times that of pure alumini...

An Ultra High Frequency (UHF) half-loop antenna used in Radio Frequency Identification (RFID) systems is proposed with a planar patterned metamaterial structure of compact size. The size of the planar patterned metamaterial structure is (0.20λ*0.20λ*0.0023λ) mm. This antenna consists of two metamaterial unit cells having negative permittivity and permeability. Simulation results of input return...

one way to increase the heat transfer is to use perforated twisted tapes with different hole diameters, which largely improve heat transfer with an increase in the heat transfer area at the constant volume and more mixed flow. in the previous studies, the effect of nanofluids with perforated twisted tapes is less studied. in this work, the performance of water / iron oxide nanofluid in a double...
