Accurate modeling of metals (plasmonics) and semiconductors. 2. Setting Up Your First Simulation

A finer mesh increases accuracy but requires more RAM and time. Start with a "Mesh Accuracy" of 2 or 3 for testing. Step 3: Add Sources and Monitors lumerical fdtd tutorial pdf

Use a Plane Wave for metasurfaces or a Mode Source for integrated waveguides. Define your frequency/wavelength span here. Monitors: These "record" the data. Index monitors verify the geometry. Accurate modeling of metals (plasmonics) and semiconductors

The Lumerical workflow is generally divided into four main stages: Step 1: Define the Geometry Use the Layout tab to import or create structures. Start with a "Mesh Accuracy" of 2 or 3 for testing

Frequency-domain field profile monitors visualize the E-field.

Always run a few simulations with increasingly finer meshes to ensure your results have converged to a stable value.

Use the Lumerical Script File (.lsf) to automate sweeps. For example, you can script a loop to find the optimal width of a waveguide. 5. Where to Find More Resources
