Abstract: A 3D wideband high-gain circularly-polarized array antenna (CPAA) with low radar cross section (RCS) is presented in this manuscript. Its element contains four 3D radiation structures fed by ...

Abstract: Wearable biomagnetic field mapping with multiple-channel atomic magnetometers (AMs) requires low-cost microfabricated rubidium vapor cell arrays (RVCAs) of high performance. In this letter, ...

Zhou and colleagues seeks to tick all the boxes, with a recent paper (preprint, open access) in Nature Photonics describing their 3D-RAPID system. This system features a 9×6 camera grid ...
