Fano resonance has been widely used in hot fields such as nano-metamaterial.Through a simpleharmonic oscillator model, the dynamics mechanism of Fano resonance was deduced in detail, and theresonance system of double-coupling harmonic oscillator was designed. The concept of Fano resonance was firstintroduced into the university physics experiment teaching system.  We also provides detailed experimentaldesign and application scheme ,which is an effective supplement to the concept of resonance in the universityphysics experimental teaching system ,  and also enhances the frontier and comprehensiveness of experimenta courses.
