Model & Assumptions Experimental
- Model
- Full-wave retarded boundary element method (BEM). Surface currents are expanded in Raviart–Thomas basis functions on a triangular mesh; Maxwell's equations are solved via surface integral equations.
- Assumptions
- Piecewise-homogeneous media (sharp interfaces), local and isotropic dielectric response, no spatial dispersion.
- Validity
- Applicable to arbitrary particle shapes and sizes. Accuracy depends on mesh quality — finer meshes improve convergence but increase computation time (runs in-browser via Pyodide).
- Limitations
- Browser memory limits mesh resolution (~1000 triangles practical). No periodic boundaries, no substrate, no non-local corrections. First load downloads ~35 MB (Pyodide + dependencies).
