In this study, a square-shaped single-ring SRR unit cell is modeled by using a suitable two-port resonant circuit representation that accounts for the conductor loss and dielectric loss effects as well. Capacitive and inductive coupling effects between adjacent SRR unit cells are also described by the two-port equivalent circuit approach. Finally, the resonance frequency of an infinitely long SRR array is estimated using its equivalent circuit model and compared to the value of the resonance frequency obtained by HFSS simulations for the same array topology.
