Polytechnic University of MilanItaly

Dr. Marco G. Beghi graduated in 1979 in Nuclear Engineering at Politecnico di Milano, Italy. He spent one year at University of California, Los Angeles. In 1984 he became research fellow at the Department of Nuclear Engineering, Politecnico di Milano, and in 2003 associate professor of Condensed Matter Physics. He was member of government bodies of Politecnico: Board of Administrators and Academic Senate. Presently he is in the Micro- and Nanostructured Materials Laboratory of the Department of Energy, Politecnico. Since 1991 he has been teaching Experimental Physics, Condensed Matter Physics, and Technology of Nuclear Materials, to undergraduate and graduate students of Nuclear and Materials Engineering. His experimental research concerns the physics of materials. He analysed the mechanical behaviour of metals in terms of dislocation dynamics and irreversible thermodynamics. He then worked on thin films and their properties, exploiting Brillouin spectrometry to measure the elastic properties. He co-authored over seventy peer reviewed publications.

The concept of acoustic wave is a pervasive one, which emerges in any type of medium, from solids to plasmas, at length and time scales ranging from sub-micrometric layers in microdevices to seismic waves in the Sun's interior. This book presents several aspects of the active research ongoing in this field. Theoretical efforts are leading to a deeper understanding of phenomena, also in complicated environments like the solar surface boundary. Acoustic waves are a flexible probe to investigate the properties of very different systems, from thin inorganic layers to ripening cheese to biological systems. Acoustic waves are also a tool to manipulate matter, from the delicate evaporation of biomolecules to be analysed, to the phase transitions induced by intense shock waves. And a whole class of widespread microdevices, including filters and sensors, is based on the behaviour of acoustic waves propagating in thin layers. The search for better performances is driving to new materials for these devices, and to more refined tools for their analysis.
