The focusing of light represents a key functionality, which can efficiently be achieved through wavefront shaping via metasurfaces (MSs). Remote light focusing requires interfacing these ultraflat photonic structures with optical fibers, which is har

Metasurfaces have revolutionized photonics due to their ability to shape phase fronts as requested and to tune beam directionality using nanoscale metallic or dielectric scatterers. Here we reveal inverse metasurfaces showing superior properties comp

Plasmon-induced catalysis of the thiols 4-aminothiophenol (ATP) and 4-nitrothiophenol (NTP) has been investigated in numerous studies. Currently, two reaction pathways are discussed in the literature, one leading to dimerization to 4,4’-dimercaptoa
