摘　　要：Fano共振现象在纳米超材料等前沿热点领域有非常广泛的应用,通过一种简单的耦合谐振子模型,详细推导了Fano共振的动力学机理,设计了双耦合谐振子共振系统,将微观量子物理领域中Fano共振的概念引入到大学物理实验教学体系中,并提供了详细的实验设计与应用方案,对大学物理实验教学体系中关于共振的概念是一种有效的补充,同时也提升了实验课程的前沿性和综合性。Fano resonance has been widely used in hot fields such as nano-metamaterial.Through a simple harmonic oscillator model,the dynamics mechanism of Fano resonance was deduced in detail,and the resonance system of double-coupling harmonic oscillator was designed.The concept of Fano resonance was first introduced into the university physics experiment teaching system.We also provides detailed experimental design and application scheme,which is an effective supplement to the concept of resonance in the university physics experimental teaching system,and also enhances the frontier and comprehensiveness of experimental courses.
