3D Active Janus Antenna: Paper Published by Laser & Photonics Reviews
Our work on a 3D active Janus antenna is now published online by the Laser & Photonics Reviews. We report, to our best knowledge, the first 3D Janus source that can be excited by a co-axial cable, instead of via scattering an incident wave. With this device, demonstrate directional waveguide coupling over a bandwidth exceeding 20%, with a power efficiency over 50x improved from a passive Janus source. Congratulations to Xue Bo (PhD student) and Kayode (postdoc) on this work!
