В ходе геофизического семинара с.н.с. лаборатории динамических проблем сейсмики к.ф.-м.н. Аркадий Маркович Айзенберг рассказал о результатах своих исследований за последние пять лет. Темой доклада стало «Развитие теории операторов прохождения, распространения и дифрагирования для применения в прямых и обратных волновых задачах в сложно-построенных средах».
В своих работах А.М. Айзенберг развивает строгую линейную теорию волновых процессов с акцентом на одновременное решение двух главных проблем теоретической геофизики: синтез интерференционного волнового поля и анализ структуры волнового поля.
А.М. Айзенберг на семинаре
– Использование волновой (не корпускулярной!) концепции позволяет разрабатывать теоретический аппарат синтеза и анализа, который может вычислять как отдельные волновые моды, имеющие физическую природу, так и их интерференцию, – отметил Аркадий Маркович. – Применяемый подход инвариантен относительно материальных и геометрических параметров модели среды и может быть обобщен на более реалистические модели среды (упругие, пористо-трещиноватые и т.п.).
По словам специалиста, явная аналитическая форма структуры полного волнового поля позволяет находить взаимно-однозначное соответствие между отдельными фрагментами волнового поля и локальными элементами среды.
Также Аркадий Маркович рассмотрел аспекты новой теории, связанные с элементами математического описания материальных и геометрических параметров геологических тел.
Презентация вызвала большой интерес со стороны слушателей. В продолжительной и конструктивной дискуссии приняли участие заведующий лабораторией многоволновых сейсмических исследований д.ф.-м.н. В.А. Чеверда и г.н.с. лаборатории глубинных геофизических исследований и региональной сейсмичности д.г.-м.н. В.Д. Суворов. Своё мнение высказали в.н.с. лаборатории вычислительной физики горных пород д.ф.-м.н. Б.П. Сибиряков и н.с. лаборатории естественных геофизических полей Д.А. Кулешов.
Завершая семинар, А.М. Айзенберг поблагодарил коллег за интересные вопросы и предложения.
