Broadband Operation of Binary Metasurfaces: Limitations and Perspectives
IEEE AccessIn this paper, physical prerequisites of the broadband operation of reflective intelligent surfaces (RIS) implemented as periodically non-uniform metasurfaces (MSs) of binary type are elucidated. The general relation for the maximal operational band of a

A Generalization of Arrow’s Lemma on Extending a Binary Relation
International Journal of Mathematics and Mathematical Sciences, 2019 By examining whether the individualistic assumptions used in social choice could be used in the aggregation of individual preferences, Arrow proved a key lemma that generalizes the famous Szpilrajn’s extension theorem and used it to demonstrate the ...

Advanced Functional Materials, EarlyView.PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...

Nano‐Patterned CuO Nanowire Nanogap Hydrogen Gas Sensor with Voids
Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.Sub‐5‐ppb hydrogen (H2) detection and sub‐10‐s response and recovery times are achieved based on nano‐patterned polycrystalline CuO nanowires nanogap gas sensors with voids using electron‐beam lithography and unique annealing processes. Pre‐H2 annealing, void‐generating oxidation, and downscaled nanogap electrodes are key to improving the sensing ...
