Abstract
Numerical modeling was carried out, the results of which are in good agreement with the radiophysical experiment for each of the structures, namely in the magnon-crystalline structure, which is a spin-wave transmission line based on a metasurface in the form of an YIG structure and permalloy disks on a polycor substrate with sputtered micristrip antennas. Amplitude-frequency characteristics plots as well as magnetization distribution maps were plotted. The transmission spectrum of the structures and opacity bands as the disk diameter was varied were also measured.
