In the field of nanophotonics, where light interacts with structures smaller than its own wavelength, analytical solutions to Maxwell’s equations are often impossible. Computational electrodynamics becomes not just helpful, but necessary. Among the most powerful and widely adopted tools is Lumerical FDTD, a software package that solves Maxwell's equations directly using the Finite-Difference Time-Domain (FDTD) method. This essay provides a tutorial-based introduction to Lumerical FDTD, outlining its fundamental principles, core workflow, and practical considerations for running accurate and efficient simulations.
: Define the physical geometry by adding primitives like rectangles, circles, or complex objects from the Object Library Simulation Region lumerical fdtd tutorial
In this tutorial, we have demonstrated how to set up and run a simple FDTD simulation using Lumerical. We have created a 2D simulation domain, defined materials, created a structure, added sources and monitors, and run the simulation. By analyzing the results, we can gain insight into the behavior of light in optical systems. Bridging Theory and Simulation: A Tutorial Approach to
