Zusammenfassung:In this study, squire ring resonator structure (SRR), which can be used as an materials sensor based on electromagnetic metamaterials absorber in microwave S-band regime. The SRR is contain squire copper ring and hole on the top, FR4 in the middle layer and copper film at the bottom. The sensitivity of the resonance frequency to the material type was numerically examined in the CST Microwave Studio (MWS) environment. In these analyzes, the hole dielectric constant of material was changed from 4.3 to 1. Within the three different materials (FR4, oil and vacuum). It is shown that the absorption wavelength displays worthy blue-shift with the increasing dielectric constant of material. Furthermore, the simulation results indicate that the sensitivity of SRR is very good, which makes SRR structure be an ideal detection for material type.
