Title:Geometric Aspects of First Order Field Theories in Piezoelectricity and MagnetohydrodynamicsAuthor(s):Markus Schöberl, Andreas Siuka, Kurt SchlacherAbstract:his paper deals with geometric properties of first order Hamiltonian systems in field theory. We focus on the physical system properties, especially on energy flows as well as on an adequate formulation of input and output maps including differential operators. The proposed machinery is demonstrated on modeling of piezoelectric structures and magnetohydrodynamical systems.Booktitle:Proceedings, 2010 International Conference on Electromagnetics in Advanced ApplicationsISBN:978-1-4244-7367-0Page Reference:page 55-58, 4 page(s)Publishing:2010
