A Multitude of Simulation
Models Required
It is not feasible to conduct multiscale optical simulations using a singular simulation model.
Geometrical Optics Alone
Isn’t Enough
For example, geometric-optical simulation models are either unavailable for certain structures and components or, when they do exist, their accuracy is often limited.
Rigorous Solvers Crucial but Narrow Real-World Applicability
Conversely, rigorous simulation models such as Finite Difference Time Domain (FDTD) or FMM (Fourier Modal Method, aka RCWA) consistently deliver high accuracy. However, their use is restricted to structures covering an area of roughly (50λ)2. Otherwise, both the computational time and resource demands would become infeasible.
It’s impossible to rely on a single simulation model for multiscale simulation; you need a diverse array of models.
Many Tailored Simulation Models Needed ...
In multiscale optical simulations, customized simulation methods are crucial to handle the varying structural scales of optical elements and objects, striking a perfect balance between computational speed and precision.
... And Offered by VirtualLab Fusion
In VirtualLab Fusion, you have access to an extensive collection of simulation models, from the Fourier Modal Method (FMM) Maxwell Solver to geometrical optics-based models. Each optical component is equipped with a customized model from this selection, ensuring results that are both fast and precise.
