Micromagnetic modeling was performed in the MuMax3 environment. It is established that additional hybrid modes on the dispersion characteristic for a magnon crystal near each main width mode are formed. The ratio of ridge to groove widths affects the energy distribution between hybrid modes and the cutoff frequency of the main modes. The influence of the ridge/groove ratio on the formation of band gaps based on dispersion and amplitude-frequency characteristics is analyzed. It is shown that the most pronounced band gaps are observed for large ridge/groove width ratios. Also, an increase in the ridge/groove ratio and an increase in the groove depth leads to an increase in the number of orders of pronounced Bragg resonances.</p></abstract><trans-abstract xml:lang="ru"><p>Приведены результаты исследования особенностей распространения спиновых волн в магнонном кристалле на основе наноразмерной ферромагнитной пленки с периодической системой канавок на поверхности. Микромагнитное моделирование проведено в среде MuMax3. Установлено, что на дисперсионной характеристике магнонного кристалла вблизи каждой основной ширинной моды формируются дополнительные гибридные моды. Соотношение ширин столбик/канавка влияет на распределение энергии между гибридными модами и на частоту отсечки основных мод. Проанализировано влияние соотношения ширин столбик/канавка на формирование запрещенных зон на основе дисперсионных и амплитудно-частотных характеристик. Показано, что наиболее выраженные запрещенные зоны наблюдаются для больших соотношений ширин столбик/канавка. Также увеличение соотношения ширин столбик/канавка и увеличение глубины канавки приводит к увеличению количества порядков выраженных брэгговских резонансов<italic>.</italic></p></trans-abstract><kwd-group xml:lang="en"><kwd>spin waves</kwd><kwd>magnon crystal</kwd><kwd>band gap</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>спиновые волны</kwd><kwd>магнонный кристалл</kwd><kwd>запрещенная зона</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Российский научный фонд</institution></institution-wrap><institution-wrap><institution xml:lang="en">Russian Science Foundation</institution></institution-wrap></funding-source><award-id>23-79-30027</award-id></award-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Российский научный фонд</institution></institution-wrap><institution-wrap><institution xml:lang="en">Russian Science Foundation</institution></institution-wrap></funding-source><award-id>19-79-20121</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Гуляев Ю.В., Никитов С.А. // ДАН.
