This paper present the concept of #aperture #sharing for generating #concentrically #embedded #orbital #angular #momentum (#OAM) -carrying beams is presented. Such a methodology provides embedded beams of various OAM modes which are launched toward a single direction through a shared aperture of #transmitarray (#TA), while having a spatial division between them. In this manner, the transmitted beams are initially separated by the hardware at the transmitter level. A novel #circularly #polarized (#CP) substrate-coupled unit cell is designed and used as the elemental components on the aperture of the TA. Three prototype TAs are realized for investigating different cases of the OAM modes embedding and verifying the effectiveness of the proposed method. ---- Arash Valizade Shahmirzadi, Zahra Badamchi, Bahareh Badamchi, Harish Subbaraman More details can be found at this link: https://lnkd.in/etD2nnAj

The future of cellular data transfer could lie in "curving" light beams midair to deliver 6G wireless networks with blazing-fast speeds — bypassing the need for line of sight between transmitter and receivers. In a new study published March 30 in the journal Nature's Communications Engineering, researchers explained how they developed a transmitter that can dynamically adjust the waves needed to support future 6G signals. The most advanced cellular communications standard is 5G. Expected to be thousands of times faster, 6G will begin rolling out in 2030, according to the trade body GSMA. - - - #Space #6G #spaceze #cellular #nasa #spaceship #spacex #spacestation #universe #astronomy #astronaut #stars #spaceshuttle #explore

It would seem an up to 90-minute delay in receiving a distress signal with a first-generation ELT-DT defeats the purpose of autonomous distress tracking.
