Tunable Elliptical Split Ring Resonator Using Single Varactor Diode

Abstract: The scope of this paper is to examine the effect of changing the structure of split ring resonator SRR from circular to an elliptical shape. The theoretical analysis of circular SRR (CSRR) is first examined and its results are compared with the simulated ones. Comparison between both configurations is also introduced. The new elliptical SRR (ESRR) can be adapted to operate in a multi-range of frequencies. The effect of gap position in ESRR resonant is also examined. When both gaps are moved but still aligned, … Show more

“…The impedance of metamaterials can be matched to the impedance of free space by alteration of permittivity ( ε ) and permeability ( µ ). In this context, researchers have developed and investigated the extraordinary properties of metamaterials and have come up with many designs, such as complementary split-ring resonators [ 12 ], elliptical split-ring resonators [ 13 ], omega-shaped metamaterials [ 14 ], and so on. Due to their unique electromagnetic properties, they can be used in invisibility cloaks [ 15 ], gain enhancement [ 16 ], filters [ 17 ], sensors [ 18 ], highly directive subwavelength cavity antennas [ 19 , 20 , 21 ], etc.…”
