Pre-training by numerous image data has become defacto for robust 2D representations. In contrast, due to the expensive data processing, a paucity of 3D datasets severely hinders the learning for high ...

In this paper, a 3D beamforming phased array with 2D stacked tunable Nolen matrix is presented. The fundamental building block - tunable Nolen matrix is proposed to relax phase tuning range of phased ...
