Theoretical Analysis of Lattice-Mediated Plasmon Resonance Using Finite-Difference Time-Domain Method

Although much progress has been made on lattice plasmon mode (LPM), there is still a lack of systematic studies on LPM generation; questions remain unanswered on topics such as high-order LPM generation, LPM generation from near-coupling complex elements, and modulation of incidence energy. Here, we systematically evaluated the properties of multiple high-order LPM, energy flow modulation of incident polarization, element, angle of incidence, and hybrid of dual lattice using the finite-difference time-domain method. This study presents a clear illustration of LPM and will help on further development of LPM and plasmonics-based fields.
