Journal paper "Directional dipole dice enabled by anisotropic chirality", authored by Dr Alex Wong (Assistant Professor of EE), Dr Dangyuan Lei (Associate Professor of MSE), and Dr Shubo Wang (Assistant Professor of PHY), has been published in The Proceedings of the National Academy of Sciences (PNAS) on 12 June 2023.
PNAS is regarded as one of the world's top academic journals. It is so excited that Dr Wong as a young faculty member having paper published in such an international top journal.
According to Dr Wong: “The directional dipole dice is a helical element that can act as a circular dipole, Huygens dipole or Janus dipole when excited by plane waves with the appropriate direction and polarization. These dipoles have distinctive near-field directionalities which allow one to direct electromagnetic wave coupling into waveguides in different directions, like how traffic lights direct traffic flow through intersections.”.
