摘要

Abstract

Recent experiments have demonstrated that synthesized complex-frequency waves can impart a virtual gain to molecule sensing systems

which can effectively restore information lost due to intrinsic molecular damping. The enhancement notably amplifies the signal of trace molecular vibrational fingerprints

thereby substantially improving the upper limit of sensitivity.
