In undergraduate courses on classical electromagnetism, it is taught that a perfect conductor
expels the electromagnetic (EM) field, and hence its surface is not able to support the …

Plasmonic metasurfaces, which can be considered as the two-dimensional analog of metal-
based metamaterials, have attracted progressively increasing attention in recent years …

Solar energy absorption is a very important field in photonics. The successful development
of an efficient, wide-band solar absorber is an extremely powerful driver in this field. We …

Electromagnetic absorbers have drawn increasing attention in many areas. A series of
plasmonic and metamaterial structures can work as efficient narrowband absorbers due to …

This Colloquium presents an overview of the research on nonlinear electromagnetic
