Meep is a free, open-source finite-difference time-domain (FDTD) simulation package for solving Maxwell's equations in 1D, 2D, 3D, and cylindrical coordinates. It is scriptable via Python, Scheme, or C++ APIs and supports MPI-based distributed parallelism for large-scale electromagnetic simulations.
Use cases
- simulate light propagation through photonic crystal structures
- model electromagnetic wave scattering from nanostructures
- compute transmission and reflection spectra of waveguides
- design and optimize metasurfaces and antennas
- simulate resonant modes and quality factors of optical cavities
- model dispersive and nonlinear optical materials
- run parallel FDTD simulations on HPC clusters
When to choose
- you need accurate time-domain electromagnetic simulation with a permissive workflow and Python scripting
- you want to model complex materials including anisotropic, dispersive, nonlinear, or gyrotropic media
- you need MPI-parallel simulations across 1D/2D/3D geometries
- you are doing photonics, metamaterials, or nanooptics research on a budget
When to avoid
- you need frequency-domain-only solvers with simpler setup (consider FEniCS or commercial tools)
- you require circuit-level RF/EM simulation rather than full-wave FDTD
- you need a GUI-driven commercial-grade workflow with vendor support
- your problem is better served by finite-element methods for irregular geometries
