RESEARCHERS
The activities of recent years in this research area consists of the development and study of physical properties of thick films, for the development of which several techniques are used. The research is performed in collaboration with the Department of Mechanical Engineering of the University. Several experienced researchers are involved along with PhD and postgraduate students.RESEARCHERS
The research field of the group includes the study of dynamics of non-linear circuits and systems, with an emphasis on the study of their chaoticbehaviour. In particular, the group studies the possibilities for synchronization of two chaotic circuits, as well as the control of chaotic behaviour. The study is both experimental and theoretical (with the help of computer simulations).
