Physics and chemistry of the ozone layer and propagation of solar radiation through the atmosphere. Interactions of solar radiation with atmospheric constituents (atmospheric aerosols and atmospheric gases). Radiative transfer modeling and impacts of UV radiation. Solar energy.
Research is carried out in the area of atmospheric remote sensing with the help of laser sources (lidar techniques), focusing mainly on particulates and ozon.
i. Diagnostic applications (electrical impedance tomography
ii. Therapeutic applications (microwave hyperthermia, RF ablation)
iii. Non-ionising radiation dosimetry (SAR assessment of telecommunications equipment).
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.
