Abstract: This article presents a 3D-printed dielectric resonator antenna (DRA) array operating in the K-band, which incorporates a 3D-printed polarizing radome to achieve circular polarization. The ...
Abstract: Synthetic Aperture Radar Tomography (TomoSAR) is a standard tool for 3D radar imaging, which overcomes the limitation of 2D geometric distortion by using the baseline diversity. Repeated ...
Scientists mapped a hidden "sea of light" from hydrogen 9–11 billion years ago, revealing how the early universe was structured.
