摘要：
In this paper, we report the fabrication and characterization of a V-shaped split ring resonator (SRR) metamaterial and have shown that it is possible to tune a negative refractive index by changing the angular gap of V-shaped SRR. Our experimental characterization results are well supported by simulation results using the FDTD method. The reported design of a V-shaped SRR structure has the distinctive advantage of having its capacitance varied by changing the angular gap between its arms. It is also observed that the electromagnetic parameters (such as permittivity and permeability) of metamaterials can be tuned as per our requirement by varying the angular gap.
