This study aims to design and analyze a single split-ring resonator (SRR)-based microwave metamaterial able to detect the composition of vegetable oil and gasoline mixtures. The vegetable oil and gasoline mixture samples are attached to a single SRR-based microwave metamaterial. In this experiment, the single SRR microwave metamaterial is fabricated by scribing silver ink onto paper. The samples comprise 20%, 40%, 60%, and 80% vegetable oil and gasoline mixtures. The single SRR microwave metamaterial is able to detect the volume composition of the vegetable oil and gasoline mixtures by shifting resonance frequency between metamaterial samples with and without the mixtures of vegetable oil and gasoline. The Δf of metamaterials treated with 20%, 40%, 60%, and 80% mixtures of vegetable oil–gasoline samples obtained experimentally are 0.13 ± 0.054 GHz, 0.18 ± 0.056 GHz, 0.19 ± 0.098 GHz, and 0.25 ± 0.054 GHz, respectively. The permittivity and refractive indexes of the single SRR microwave metamaterial are significantly altered for vegetable oil and gasoline samples of varied compositions. Polarization in the SRR gap is the critical feature used to describe this study's detection ability. © 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
