Whole-mount 3D imaging at the cellular scale is a powerful tool for exploring complex processes during morphogenesis. In organoids, it allows examining tissue architecture, cell types, and morphology ...

Direction-of-Arrival (DOA) estimation capability of sensor arrays is greatly influenced by geometric configuration of arrays. We proposed a new type 2-D planar array, improved Archimedean spiral array ...

In this letter, a near-field focused array antenna is applied to two-dimensional microwave imaging, which steers its focus on the designed focal plane by changing the operating frequency and by phase ...
