Finite difference time domain software

It covers every detail of FDTD in simple terms and with high quality visualizations. By the end, you will have developed a fully functional 1D FDTD simulation that calculates and displays reflectance and transmittance from a device and animates the field interacting with the device.

This course only contains the codes and does not explain or derive the FDTD method. See more application notes. RSoft Photonic Device Tools. Photonic System Tools.

Adjoint solver for inverse design and topology optimization. Visualization routines for the simulation domain involving geometries, fields, boundary layers, sources, and monitors. Time-Domain Simulation A time-domain electromagnetic simulation simply evolves Maxwell's equations over time within some finite computational volume, essentially performing a kind of numerical experiment.

Major applications include: Transmittance and Reflectance Spectra — by Fourier-transforming the response to a short pulse, a single simulation can yield the scattering amplitudes over a broadband spectrum. Resonant Modes and Frequencies — by analyzing the response of the system to a short pulse, one can extract the frequencies, decay rates, and field patterns of the harmonic modes of lossy and lossless systems including waveguide and cavity modes.
