On Nov.7, Dr. Tobias M Muller, the research team leader at the Earth Science Division of Commonwealth Scientific and Industrial Research Organization (CSIRO), Australia visited IACAS for academic exchanges, invited by Prof. WANG Xiuming, director of Ultrasonic Physics and Exploration Laboratory of IACAS.

Dr. Muller prepared a lecture of "Poroelasticity Theory and Wave Attenuation", focusing on propagation of wave in porous, composite material such as rocks and effects of dynamic poroelasticity framework, scattering attenuation, viscous boundary layer and inhomogeneous relaxation and connectivity degree of fracture networks on them.

In his lecture, Dr. Muller used many living examples to illustrate the relationship between poroelasticity and wave attenuation. More than thirty staff and students from IACAS attended his lecture and discussed the details of the lecture actively with Dr. Muller.

Dr. Muller is an internationally famous geophysicist who has got many achievements in the fields of waves in random media, poroelasticity and rock physics.
