In this roadmap article, we have focused on the most recent advances in terahertz (THz)
imaging with particular attention paid to the optimization and miniaturization of the THz …

Metasurfaces, the ultrathin, 2D version of metamaterials, have recently attracted a surge of
attention for their capability to manipulate electromagnetic waves. Recent advances in …

Metamaterials are composed of periodic subwavelength metal/dielectric structures that
resonantly couple to the electric and/or magnetic components of the incident …

Here we present a roadmap on Photonic metasurfaces. This document consists of a number
