首先建立了有限宽度、具有任意参数的多层薄膜结构中的静磁表面波（ ＭＳＳＷ） 宽度模普适色散方程，这一理论包含了利用多层薄膜控制静磁表面波色散特性的所有情形，使研究更加符合实际．对多周期的［（ＹＩＧ／ＧＧＧ）１０／ 金属层］ 多层膜结构窄样品中ＭＳＳＷ 宽度模色散特性进行了数值计算，ＭＳＳＷ 在多层窄样品中的工作主模为一阶宽度模式，多层膜的周期及参数可以有效地控制ＭＳＳＷ 的色散特性，样品宽度效应也会对色散特性产生影响．
First of all, we establish the mode dispersion equation of static surface area (MSSW) width in multi-layer thin film structure with finite width and arbitrary parameters. This theory includes all the cases that the multi-layer thin film is used to control the dispersion characteristics of static magnetic surface wave. Make research more realistic. The numerical simulation of the MSSW width-mode dispersion in a multi-period thin-film multi-layered structure with [(YIG / GGG) 10 / metal layer] is performed. The main mode of MSSW in the multi-layer narrow sample is the first- The period and parameters of the film can effectively control the dispersion characteristics of MSSW, and the sample width effect also has an impact on the dispersion characteristics.
