摘要：
Here we present an optimized multilayer structure for sensitive characterization of thin-film aqueous solutions with reflection terahertz time-domain spectroscopy. The theoretical sensitivity is compared with a recently published sensitive structure and other ordinary geometries. Glucose solutions with a 5% concentration gradient are measured for accuracy verification.
