Experimental Analysis of Biasing Voltage Generation in Wave-Controlled RIS
Miguel Saavedra-Melo, Benjamin Bradshaw, Vanessa Yao +3
Reconfigurable intelligent surfaces (RISs), an emerging technology proposed for inclusion in next generation wireless communication systems, are programmable surfaces that can adap…
Double-Corrugated Degenerate Band-Edge Oscillator Driven by an Electron Beam
Miguel Saavedra-Melo, Robert Marosi, Nelson Castro +2
The properties of a degenerate band-edge (DBE) oscillator based on the synchronous interaction between a linear electron beam synchronized with four degenerate electromagnetic mode…
AI-Driven Optimization of Wave-Controlled Reconfigurable Intelligent Surfaces
Gal Ben Itzhak, Miguel Saavedra-Melo, Ender Ayanoglu +2
A promising type of Reconfigurable Intelligent Surface (RIS) employs tunable control of its varactors using biasing transmission lines below the RIS reflecting elements. Biasing st…
Wideband Glide-Symmetric Double-Corrugated Gap-Waveguide Traveling-Wave Tube for Millimeter Waves
Miguel Saavedra-Melo, Nelson Castro, Robert Marosi +2
We explore the use of glide symmetry (GS) and electromagnetic bandgap (EBG) technology in a glide-symmetric double corrugated gap waveguide (GSDC-GW) slow wave structure (SWS) for…
