Abstract
This study focuses on numerical analysis of a metamaterial based on a Split Ring Resonator (SRR), using wave-based electromagnetic modeling conducted in CST Studio Suite and validated using HFSS. To characterize the magnetic response of the structure, we apply a Lorentz model to the real and imaginary parts of the extracted relative permeability, enabling the estimation of key parameters such as the resonance frequency, damping factor, and magnetic susceptibility.
We further investigate the influence of SRR geometric variations—specifically substrate thickness, gap size, and ring width—on the electromagnetic response. Simulation results reveal that reducing substrate thickness and gap size enhances the resonance strength, leading to deeper dips in the transmission coefficient (S21) and more pronounced negative permeability. Increasing the ring width causes a slight shift in the resonance and affects the quality factor. These findings provide valuable design guidelines for engineering tunable metamaterials based on SRR structures.
