Real time detection and recognition of micro-poisons in aqueous solutions and atmosphere using perfect absorber metamaterial in millimeter wavelength regime

In this study we present a concept of real-time and very inexpensive sensor for detection and recognition of micro poisons in aqueous solutions. The method is based on combination of advanced millimeter Wavelength (MMW) spectroscopy system and perfect absorber metamaterial (MM). The designed absorption line of the perfect absorber MM moves slightly due to substance presents in vicinity to the perfect absorber. This change is measured by a high-resolution and sensitive MMW spectroscopy system.
