| Abstract: |
| Using the coherent superposition principle,the transmittance formula and frequency formula of SH wave defect mode are derived in 1D doping phononic crystal,and the coherent superposition theory is established.The coherent superposition theory,the transfer matrix theory and the resonance theory are compared.The coherent superposition theory has advantages of the transfer matrix theory and the resonance theory,and the coherent superposition theory does not have disadvantages of the transfer matrix theory and the resonance theory.The coherent superposition theory is a better way to study SH wave defect mode of phononic crystal. |
