All-dielectric concentration of electromagnetic fields at the nanoscale: the role of photonic nanojets

J Zhu, LL Goddard - Nanoscale Advances, 2019 - pubs.rsc.org
The photonic nanojet (PNJ) is a narrow high-energy beam that was originally found on the
back side of all-dielectric spherical structures. It is a unique type of energy concentration …
