A 3D-printed piezoelectric metamaterial uses topology-driven charge transport to locate underwater sound sources from a single compact transducer, replacing bulky hydrophone arrays.
Abstract: Phased arrays with wide beam-scanning range and low cross polarization are significant for the millimeter-wave communication. To achieve this goal, this article presents a novel method of ...
Abstract: This paper presents a millimeter-wave (mmWave) phased array antenna (PAA) design that reduces the required number of phase shifters while achieving high gain and low grating lobes for both ...
