This book is devoted to theoretical methods used in the extreme circumstances of very strong electromagnetic fields. The development of high power lasers, ultrafast processes, manipulation of electromagnetic fields and the use of very fast charged particles interacting with other charges requires an adequate theoretical description. Because of the very strong electromagnetic field, traditional theoretical approaches, which have primarily a perturbative character, have to be replaced by descriptions going beyond them. In the book an extension of the semi-classical radiation theory and classical dynamics for particles is performed to analyze single charged atoms and dipoles submitted to electromagnetic pulses. Special attention is given to the important problem of field reaction and controlling dynamics of charges by an electromagnetic field.

Structure of molecules.- Electrodynamics.- Charge in electromagnetic wave.- Confinement of charge.- Controlling dynamics of a bound charge.- Atom in electromagnetic field.- Very short electromagnetic pulse.- Radiation by charge.- Field reaction.- Dynamics of single charge.- Dynamics of dipoles.- Level shifts.

Prof. Slobodan Danko Bosanac Graduated in Theoretical Physics from the University of Zagreb in 1968 and in 1972 received Ph. D. from the University of Sussex, UK, in Molecular Sciences. After postdoctoral research at the University of Bristol, UK, in 1974 obtained a research position at the R. Boskovic Institute, Zagreb, which had been since then his permanent domicile institution.  During his research carrier published around 100 papers, three books and was principal investigator in several international science projects. Prof. Bosanac was visiting professor at a number of universities:  University of Florida, University of Kaiserslautern, MPI fur Stromungsforschung in Gottingen,  University of Sussex, Harvard University,  MIT, Universidade Federal de Minas Gerais, to mention few.  For his research received two State prices in science, in 1997 and 2013.

His field of research is atomic and molecular physics, electromagnetic interaction with charges,astrophysics. In 1986 he initiated interdisciplinary conferences under a general title Brijuni Conferences that since then run continuously on a biannual basis. Prof. Bosanac is a president of the Croatian branch of the US based organization Center for Inquiry whose primary aim is promotion of science. He was also recently appointed head of the Swiss Space Systems branch for Croatia, with a general aim of setting up Space Center Croatia with the central object the Space Port.
