Although a relatively new area of nanoscience, nonlinear plasmonics has become a fertile
ground for the development and testing of new ideas pertaining to light–matter interaction …

The multipolar decomposition of electromagnetic sources is an important tool for the study of
light–matter interactions in general, and optical materials in particular. Here, a report is given …

Being motivated by the recent prediction of high-Q modes in subwavelength dielectric
resonators inspired by bound states in the continuum (BIC), we study the second-harmonic …

We report a strategy for preparing cost-effective plasmonic square lattices with tunable unit
structures of circles, crosses, and circle-cross pairs on a centimeter scale. The asymmetrical …

The interaction between electromagnetic field and plasmonic nanostructures leads to both
strong linear and nonlinear behaviors. In this paper, a time-domain hydrodynamic model for …

Difference frequency generation (DFG) is an essential phenomenon for generating far-
infrared (FIR) and broadband terahertz (THz) waves, which cannot be generated by either …
