Abstract
The properties of surface plasmons create the potential for sensitivity to nanoscale environmental changes and allows for practical applications including light guiding, nanomanipulation, biosensing, high-resolution imaging, and optical switching. Grating structures have emerged as a central tool ena-bling the design of dedicated systems for modulating light-matter interactions. This contribution presents a Finite-Difference Time-Domain (FDTD) method enhanced with the Drude model, Perfectly Matched Layer, Periodic Boundary Condition, and Total Field/Scattered Field-Method that form the basis a sim-ulation environment for surface plasmon couplers. The simulations are able to cover a wide parameter space, aiding optimal design identification. Validation against experimental results on actual grating structures has been used to improve the model's accuracy and predictive capabilities. This iterative approach yields insights into efficient grating-based plasmon coupler designs thus contributing to plas-monics understanding and optimized applications.(cid:3)
