The antenna system forms an electrically steerable, phased array antenna having a beam steering angle which is constant over a very broad band of frequencies. Specific applications for the antenna system include satellite communications including tracking low earth orbiting satellites, radar systems and ...
[0010] A head-mounted display (HMD) can further integrate the DCA with the beam steering assembly. The HMD further includes an electronic display and an optical assembly. The HMD may be, e.g., a virtual reality (VR) system, an augmented reality (AR) system, a mixed reality (MR) syste...
Lasers, when used for direct cutting, can manipulate the biological tissues from macroscale (e.g., organs) to microscale (e.g., single cell) with a high energy intensity beam focused onto the tissue surface, i.e., high spatial resolution. While most soft tissues are dominated by water (...
