Что позволяет использовать простые математические модели для изучения таких явлений, как преломление волн или распространение волн в волноводах. Рациональный метод позволяет проводить аналитическое исследование коротких волн, которые делятся на элвиновские и магнитоакустические. Собственные моды магнитных аркад образуются в результате их отражения в фотосфере.</p></abstract><trans-abstract xml:lang="en"><p>MHD waves in force-free magnetic arcades describing bipolar solar active regions are studied. The geometric acoustics approximation is used in cases where the wavelength is small compared to the scale of the inhomogeneity. It allows simple mathematical models to study phenomena such as wave refraction or wave propagation in waveguides. The eikonal method allows us the analytical study of short waves which are divided into Alfven and magnetoacoustic waves. The eigen-modes of magnetic arcades are formed as a result of their reflection at the photosphere.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>магнитное поле</kwd><kwd>модели корональных магнитных структур</kwd><kwd>корональная аркада</kwd></kwd-group><kwd-group xml:lang="en"><kwd>magnetic field</kwd><kwd>models of coronal magnetic structures</kwd><kwd>coronal arcade</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">Aschwanden M.
