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.
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).
Atmospheric and Environmental Physics with emphasis on Global Change; climate change; greenhouse warming effects on the atmosphere; anthropogenic and natural variability of stratospheric and tropospheric ozone and related effects on Ultra Violet radiation, stratospheric dynamics and climate. Use and development of a fully coupled Chemistry-Climate Model (EMAC- Echam5/Messy) to simulate evolution of the atmosphere in the 21st century.
The group is involved in projects studying the phases, the microstructures and the morphology of magnetic materials focusing on correlations of structure and magnetism not only in bulk materials but in magnetic nanostructures as well. The various activities may be summarized as follows:
Α). Growth – Fabrication of magnetic materials of technological interest.
Β). Characterization and study of microstructure till the atomic level.
C). Temperature-dependent magnetic characterization.
D). Thermal, mechanical and magnetic treatments for improving the magnetic study.
E). Theoretical study and simulation of magnetic features.
