摘要
Graphene plasmonics have attracted significant attention in the past few years due to the remarkable optical and electrical properties of graphene. A highly effective method based on surface integral equations (SIE) in the frequency domain is proposed to describe both linear and nonlinear effects of graphene efficiently and accurately. Graphene, a centrosymmetric material, can possess second harmonic generation (SHG) when the conductivity is nonlocal. In this work, the fundamental harmonic (FH) of a graphene wrapped particle is studied as the first benchmark by introducing a conducting surface in SIE. Then it is modified to analyze a graphene-based patch antenna in both FH and SHG. This method can be extended to other two-dimensional materials easily, and fast multipole algorithm can be applied to accelerate the simulation.
