Transparent hybrid anapole metasurfaces with negligible electromagnetic coupling for phase engineering

All-dielectric nanophotonics has become one of the most active fields of research in modern optics, largely due to the opportunities offered by the simultaneous resonant control of electric and magnetic components of light at the nanoscale. In this rapidly evolving scenario, the possibility to desig...
