Учитывается природа обменного взаимодействия, также рассматриваются обменные граничные условия Радо-Уиртмена на основе представления их в терминах плотности свободной энергии. На основе построенной математической модели оценивается вклад в дисперсионную картину спиновых волн внешнего электрического поля разной полярности. В заключении приводится ряд случаев применения построенной математической модели при проектировании электронно-управляемых устройств направленного распространения спиновых волн, а также базовых устройств для нейроморфных вычислений.</p></abstract><trans-abstract xml:lang="en"><p>In this work, based on the dispersion characteristics of spin waves and the theory of the magnetoelectric effect, a mathematical model of a multiferroic structure behavior in a non-uniform electric field is constructed. The nature of the exchange interaction is taken into account, and the Rado-Wirtman exchange boundary conditions are also considered based on their representation in terms of free energy density. Based on the constructed mathematical model, the contribution to the dispersion pattern of spin waves of an external electric field of different polarities is estimated. In conclusion, a number of cases of application of the constructed mathematical model in the design of electronically controlled devices for the directional propagation of spin waves, as well as basic devices for neuromorphic computing, are given.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>спиновые волны</kwd><kwd>магнитоэлектрический эффект</kwd><kwd>мультиферроидные структуры</kwd><kwd>дисперсионные характеристики</kwd></kwd-group><kwd-group xml:lang="en"><kwd>spin waves</kwd><kwd>magnetoelectric effect</kwd><kwd>multiferroic structures</kwd><kwd>dispersion characteristics</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Bichurin M.
