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.
最近的实验表明，合成的复频波可以给分子传感系统带来虚拟增益，这能够有效恢复因分子固有阻尼而丢失的信息。这种增强显著放大了痕量分子振动指纹的信号，从而大幅提高了灵敏度的上限。
