Abstract :
In this letter, a new compact metamaterial unit-cell called SIR-DSR is presented. This unit-cell is designed by applying the stepped-impedance resonator (SIR) technique to a conventional double split-ring resonator (DSR) structure. The S parameters and the extracted effective relative permittivity and permeability for the presented unit-cell show a miniaturization factor of 0.75 compared to a conventional DSR. The results are validated through the fabrication and measurement of the unit-cell.
