Magnetoelectric fields for microwave chirality discrimination in enantiomeric liquids
Abstract
Chirality discrimination is of a fundamental interest in biology, chemistry, and metamaterial studies. In optics, near-field plasmon-resonance spectroscopy with superchiral probing fields is effectively applicable for analyses of large biomolecules with chiral properties. We show possibility for microwave near-field chirality discrimination analysis based on magnon-resonance spectroscopy. Newly developed capabilities in microwave sensing using magnetoelectric (ME) probing fields originated from multiresonance magnetic-dipolar-mode (MDM) oscillations in quasi-2D yttrium-iron-garnet (YIG) disks, provide a potential for unprecedented measurements of chemical and biological objects. We report on microwave near-field chirality discrimination for aqueous D- and L-glucose solutions. The shown ME-field sensing is addressed to microwave biomedical diagnostics and pathogen detection and to deepening our understanding of microwave-biosystem interactions. It can be also important for an analysis and design of microwave chiral metamaterials.
