The design of a high-efficiency Traveling Wave Tube (TWT) based on a non-conventional folded waveguide slow-wave structure (FW-SWS) operating over 34-36 GHz for naval and ground Ka-band radars is presented. The ridge vane-loaded FW structure allows a

In this thesis, an inverse source (IS) approach is considered for the constrained design of static-passive electromagnetic skins (SP-EMSs). By leveraging the ill-posedness/non-uniqueness of the IS problem at hand, a generalized solution framework is

As prominent components of the Internet-of-Things (IoT) front-end, sensors capable of intelligently collecting sensing information from the surrounding environment with increasingly lower prices are required. Planar microwave chipless sensors could b

We study second harmonic generation in dielectric nanocylinders as a function of the wavelength of the incident field and geometrical dimensions. Uncommonly, we consider a spectral range in which the emitted nonlinear signal is partially absorbed by

Recently, nonlinear optics at the nanoscale level has emerged as a promising branch of nanophotonics. In this work, we focus our attention on Aluminum Gallium Arsenide (AlGaAs) nanoantennas and metasurfaces for efficient and controlled second harmoni
