摘要

Electromagnetic sensors based on planar resonators have proven to be highly useful in thin film detection. Unfortunately, the sensor response is only based on the apparent permittivity of a target substance, and can therefore be misled by spurious material depositions of similar properties. A solution based on a combination of functionalized, selective surfaces and utilization of multi-resonant designs is demonstrated in this paper, for future integration into a terahertz sensor for specific single-cell parasites. It is shown, that the examined double split-ring structure provides highly diverse sensitivities of individual resonance modes to a small sample volume, depending on location. The baseline sensitivity is increased further by integrating a special electrode shape. A detailed analysis of the proposed concept is performed to show its limitations in spatial selectivity.
