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

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

Electromagnetic waves in the X-band (8.2–12.4 GHz frequency) are used for radar, satellite communication, and, in some countries, for wireless computer networks. Shielding allows to protect humans and electronic devices from harmful effects of thes

Protection of human eyes or sensitive detectors from high-intensity laser radiation is an important challenge in modern light technologies. Metasurfaces have proved to be valuable tools for such light control, but the actual possibility of merging mu
