Design and Analysis of Potential Phased Array Configurations for Wideband Near-Field Beamforming [PDF]
Near-field beamforming has similar challenges with beam squint like the typical far-field beamforming. This paper analyzes the spatial and frequency domain behaviors of a arc-shaped phased array with a corporate-fed and a series-fed feeding architecture.

Pattern Compensation for Faulty Phased Array Antenna Based on Deep-Learning Technique
IEEE Open Journal of Antennas and PropagationThis study proposes an approach to compensate for pattern distortion in a phased array antenna caused by antenna element failures. The proposed approach utilizes a deep-learning network explicitly trained for a phased array antenna with damaged elements ...

Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films
Advanced Functional Materials, EarlyView.Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...
