Abstract: This letter presents a broadband frequency doubler that covers the 165–260 GHz range. To achieve the broadband matching of Schottky barrier diodes (SBDs), an “Hourglass-shaped” (H-S) ...

Abstract: In this communication, we propose the vector-graph-feature-extraction (VGFE) approach to accurately and concisely characterize details of electromagnetic metasurface (EM), and then train a ...

First-person mode is Anno 117: Pax Romana’s best-kept secret. The game won’t tell you how to use it, and it’s not even mentioned in the keybinds, but it’s certainly possible to walk around like a ...

To overcome this limitation, a theoretical scheme based on entanglement swapping using sum-frequency generation (SFG) between single photons has been proposed. In this approach, by detecting the ...
