**Meet the editor**

Dr. Canet-Ferrer is visiting researcher at the ICMol, Valencia. He is the author of a number of international peer review articles and a reviewer of a number of journals in materials science, optics, and photonics. With a background in both solid state and electromagnetism, he has contributed to different fields on applied physics. His current research focus is on the design of multifunction-

al surfaces based on hybrid materials for the further generation of planar optical components.
