A Circular Split Ringdouble Negative Metamaterial Having Simultaneous Negative Permittivity and Permeability
نویسندگان
چکیده
The scope of this paper is to design and simulate a novel circular split ring structure having simultaneous negative permittivity and permeability so called double negative metamaterial or left handed material. The DNG structure consists of five circular split ring resonators on one side of dielectric medium and a couple of circular wires on other side. The complex permittivity, permeability, impedance and refractive index are determined from simulated Scattering parameters using direct retrieval method. Simulations of DNG structure are carried out using CST MWS. MATLAB is used for verification of negative values of structure’s parameter.

Negative index of refraction in metallic metamaterial comprising split-ring resonators.
We numerically investigate the negative index of refraction in a metamaterial composed of metallic split-ring resonators, which exhibits simultaneously negative permittivity and permeability without resorting to additional metallic wires. It is confirmed that, in the left-handed band, negative permittivity is generated in analogy to the cut-wire metamaterial and negative permeability comes from...

In this paper, a new X band Metamaterial (MTM) based ferrite phase shifter is presented. The phase shifter is excited by circular polarized wave base on combination of TE10 and TE01 modes in a square waveguide. In order to synthesize negative refractive index metamaterial (NIM), negative permeability of ferrite slabs in extraordinary mode is mixed with the negative permitivity of printed period...
متن کاملA Survey on Microstrip Patch Antenna using Metamaterial
Microstrip patch antennas are used for mobile phone applications due to their small size, low cost, ease of production etc. The MSA has proved to be an excellent radiator for many applications because of its several advantages, but it also has some disadvantages. Lower gain and narrow bandwidth are the major drawbacks of a patch antenna. In this paper, a survey on the existing solutions for the...
متن کاملTransmission and Reflection Properties of Composite Double Negative Metamaterials in Free Space
We report free space transmission and the first reflection measurements of a composite double negative (DNG) metamaterial, also known as a left-handed material (LHM). The metamaterial composes of the split-ring-resonators and discontinuous thin wires. Very high transmission values of the metamaterial are observed within a frequency range for which both effective permeability and permittivity ar...
