The influence of the boundary conditions of “perfect metal” and “perfect magnetic wall” being established in various combinations near or on every surface of a tangentially magnetized ferrite plate, on the possibility of undistorted transmission of useful signal through the use of surface spin waves in this structure, is theoretically studied. It was found that, depending on parameters of the structure and boundary conditions, the quasi-linear regions occupying the range of frequencies with a width from 75 to 220 MHz and the range of wave numbers width from 40 to 200 cm^–1 can occur in the dispersion characteristic of spin waves. It was demonstrated that, for undistorted transmission of the useful signal modulating the spin wave, using of the spin waves that parameters correspond to the mentioned quasi-linear regions is necessary.

在切向磁化铁氧体板的每个表面附近或每个表面上以各种组合建立的“完美金属”和“完美磁壁”的边界条件对通过使用表面自旋波无失真传输有用信号的可能性的影响在这种结构中，进行了理论上的研究。研究发现，根据结构参数和边界条件，准线性区域占据频率范围为 75 至 220 MHz，波数宽度范围为 40 至 200 cm ^–1可以发生在自旋波的色散特性中。已经证明，对于调制自旋波的有用信号的不失真传输，使用与所述准线性区域相对应的参数的自旋波是必要的。
