Split-ring resonators (SRRs) are structures that originate from the field of metamaterials and can induce effects such as negative permittivities and permeabilities . However, there is an increasing use in various fields of sensor and measurement technology [2– 4], since SRRs allow highly sensitive detection of the electromagnetic properties of a sample at or near the split capacitor. SRRs are simple electrical resonant circuits consisting of a transmission line and a ring structure with a split. Fig. 1 shows a schematic of a SRR and an equivalent simple electrical equivalent circuit.
