This terahertz MTM exhibits tunable characteristics to adjust resonances with the manipulation of switching windows 13. present a metamaterial made with Au layer on Si substrate and operating in the terahertz range. Therefore, there is a growing interest on metamaterial focusing different working frequencies those will be tuned by various stimulus such as electrical, mechanical, or optical. All the properties of these metamaterials have occurred at some fixed frequencies of interest depending on the particular geometrical arrangement in the array and with the fixed composition of the structure. A 3D acoustic metamaterial is discussed in 12 that is used to create a bandgap at the point of deep sound attenuation that can be used for noise cancellation as an acoustic filter. A negative index metamaterial is present in 11 that consists of elongated beams attached to a plate.
Metamaterial as an artificial medium exhibits some exotic properties such as negative permittivity, negative permeability, negative refractive index, which makes it suitable for various applications such as absorber 1, microwave imaging 2, bio sensing 3, antennas 4, metamaterial lensing 5, metamaterial coding 6, terahertz metamaterial absorber 7, 8, 9, and microwave devices like Bluetooth, WiMAX, GPS 5, 10. Compact size, ENG with near zero permeability and refractive index along with frequency selectivity through tuning provides flexibility for frequency selective applications of this MTM in wireless communications. Surface current, electric and magnetic fields are analyzed to explain the frequency tuning property and other performances of the MTM.

The equivalent circuit of the proposed MTM is modelled in Advanced Design Software (ADS) that exhibits a similar S 21 compared with CST simulation.
The resonance frequencies are selective in nature which can be easily tuned by varying the length of the tuning metal stubs. The calculated effective medium ratio (EMR) is 7.14 at 4.2 GHz indicates its compactness. The proposed MTM provides four resonances of transmission coefficient (S 21) at 4.20 GHz, 10.14 GHz, 13.15 GHz, and 17.1 GHz covering C, X and Ku bands with negative permittivity, near zero permeability and refractive index. Numerical simulation of the proposed design is executed in CST microwave studio. These tuning metal strips are acted as spacers between four quartiles of the resonator patch.
The quartiles are connected at the center of the substrate with a square metal strip with which four tuning metal strips are attached.

The symmetric resonating patch is subdivided into four equal and similar quartiles with two interconnecting split rings in each quartile. The proposed metamaterial is constituted on a Rogers (RT-5880) substrate with 1.57 mm thickness and the electrical dimension of 0.14λ × 0.14λ, where wavelength, λ is calculated at 4.2 GHz. The described approach can be applied to other members of the CST STUDIO product line as well.ĬST MWS is one component of the CST STUDIO SUITE™ package, which includes CST DESIGN ENVIRONMENT™, CST DESIGN STUDIO™, CST EM STUDIO™, and CST PARTICLE STUDIO™.In this paper, a tuned metamaterial (MTM) consisting of a symmetric split ring resonator is presented that exhibits epsilon negative (ENG), near zero permeability and refractive index properties for multiband microwave applications. COM and ActiveX interfaces allow behind the scenes data transfer and tight integration between the two programs. This interface allows CST MWS users to take advantage of the extensive data manipulation, signal processing, and graphics capability in MATLAB.
