Research
Scientific project
The scientific project of the laboratory is structured around three main axes:
- A scientific axis, focusing on the study and understanding of the propagation and diffusion of electromagnetic (EM) fields and mechanical waves, divided into three themes: "Multi-physical characterization of materials", "Inspection of elongated structures" and "Imaging and monitoring of the subsurface".
- A methodological axis, dedicated to the development and implementation of methodological tools for conducting research, in terms of "Numerical and physical modeling", "Information processing", and "Instrumentation and measurements".
- An applicative axis, highlighting the societal needs to be addressed by the research activities, which are further categorized by types of territories: “Cities and urban and suburban territories”, “Fluvial and rural territories” and "Maritime and coastal territories".
