A full 3D metalens is massive. Use symmetry () if the lens is circular. Usually, you simulate a small subsection (e.g., a 5 µm by 5 µm slice) to verify focusing performance.

These simulations often use "Total-Field Scattered-Field" (TFSF) sources. They are the go-to reference for biosensing applications and metallic nanoparticle scattering. 3. Advanced Integration: CMOS and Photonic ICs lumerical fdtd examples

Lumerical FDTD offers a range of features that make it a powerful tool for electromagnetic simulations: A full 3D metalens is massive

These examples are highly popular. They walk you through the "unit cell" approach—simulating a single nanopillar to create a phase map before building the full-scale lens. Advanced Integration: CMOS and Photonic ICs Lumerical FDTD

Simulate a Titanium Dioxide (TiO2) metasurface that focuses 532 nm light to a diffraction-limited spot.

Simulate a magnetic resonance in a metallic SRR unit cell.

For those new to the software, specific "starter" examples are recommended to master the simulation workflow. FDTD product reference manual - Ansys Optics
