The research activities carried out at the Microwave and Electromagnetic Compatibility Laboratory of the DIET at the University of Rome “La Sapienza” include various topics concerning the theoretical and applied electromagnetics. Particular attention is given to modeling, analysis and design of devices, circuits, systems and antennas excited with high-frequency and fast varying pulsed signals. The analysis and design concernes the active and passive devices and advanced antennas for telecommunication and wireless applications having optical quasi-optical and UWB behavior. The propagation processes, and of the related electromagnetic compatibility problems in complex environments (indoor/outdoor), as well as the interaction of the EM fields between the electronic systems and/or with the human being are further fields of application. Moreover, suitable numerical techniques are developed for the analysis and design of complex structures (devices and antennas) and systems devoted to medical diagnosis and therapy. Finally, experimental research activities are carried out on antennas, medical Radar, electrical impedance tomography, multi frequency impedance plethysmography, microwave ablation, oscillators and microwave amplifiers, measurement of the dielectric permittivity of materials (dielectric spectroscopy), and TDR measurements techniques.
