Service-Area Robust NOMA for Pinching Antennas Systems
Zoran Hadzi-Velkov, Slavche Pejoski, Jia Guo +2
Pinching-antenna systems (PASS) enable near-field beam focusing using radiating points along a dielectric waveguide, but coherent spherical-wave superposition makes their channels…
Spatially Robust Near-Field SWIPT Using Pinching Antennas: Rate-Energy Tradeoff Bounds
Zoran Hadzi-Velkov, Marija Poposka, Slavche Pejoski +1
Pinching Waveguide Antennas (PWAs) offer significant potential for simultaneous wireless information and power transfer (SWIPT) by enabling precise near-field energy focusing. Howe…
Performance Comparison Between A Simple Full-Duplex Multi-Antenna Relay And A Passive Reflecting Intelligent Surface
Armin Bazrafkan, Marija Poposka, Zoran Hadzi-Velkov +2
In this paper, we propose to investigate a single RF chain multi-antenna full-duplex (FD) relay built with -bit analog phase shifters and passive self-interference cancellation.…
Measurement of the electron charge using Schottky noise. Problem of the 6-th Experimental Physics Olympiad. Sofia 8 December 2018
Todor M. Mishonov, Emil G. Petkov, Aleksander A. Stefanov +14
Several consecutive experiments are described with a printed circuit board PCB set-up, especially designed for these experiments. Doing the consecutive experimental tasks opens up…
