Descrizione del laboratorio
The EMC2-Nano Laboratory of the Department of Astronautical, Electrical and Energy Engineering (DIAEE) of the University of Rome "La Sapienza" is located in Via delle Sette Sale 12B, Rome, Italy, close to the Church of S. Pietro in Vincoli. The Lab was established in 2006 to promote scientific research and support EMC learning activities. Prof. Maria Sabrina Sarto has been the laboratory Director since 2006. The Lab, initially founded to process nanomaterials and nanocomposite for the development of devices for EMC applications, is now provided with instruments for full mechanical and electrical characterization of materials and elctromechanical characterization of piezorestive sensors/devices. The available equipment allows tests in the frequency range from DC to 67 GHz. The lab is also equipped with microscopies for optical imaging and machining of the produced materials and devices.
Many research activities, carried out in the EMC Lab are related to research programs financed by national and international institutions, research institutes or industries. Moreover, the Lab supports exercitations for several classes of Electromagnetic Compatibility and Electrotechnics of different engineering courses (Electrical Engineering, Aerospace Engineering, Nanotechnology Engineering).
