The research project Seismic waves in complex 3-D structures (SW3D) started October 1, 1993 as a consortium research project and was devoted to seismic waves as suggested by its title. In the recent years, the research has been extended to electromagnetic waves. The research project focuses primarily on the fundamental issues of high-frequency wave propagation in complex 3-D isotropic and anisotropic structures, which go beyond the traditional approaches. The ray method and its extensions, as well as its combination with other methods are mainly applied and investigated. The emphasis is put on new, stable, more efficient and flexible algorithms for both forward numerical modelling and inversion of wave fields in 3-D inhomogeneous, isotropic and anisotropic structures. Considerable attention is also devoted to applications involving S waves, converted waves, electromagnetic waves, wave splitting and coupling in anisotropic media, particle ground motions, etc.
The principal investigators of SW3D are Vlastislav Cerveny (project leader 1993-2012), Ludek Klimes (project leader) and Ivan Psencik. Graduate and postgraduate students of the Department of Geophysics, Faculty of Mathematics and Physics, Charles University, also participate in the project.
Each year a volume of serial "Seismic Waves in Complex 3-D Structures" (ISSN 2336-3827) is issued.
The project is open to industrial companies, research institutions
