The Finite-Difference Time-Domain (FDTD) method [ 1,2,3] is a state-of-the-art method for solving Maxwell's equations in complex geometries. Being a direct time and space solution, it offers the user a unique insight into all types of problems in electromagnetics and photonics. FDTD is the gold-standard for modeling nanophotonic devices, processes, and materials. This finely-tuned implementation of the FDTD method delivers reliable, powerful, and scalable solver performance over a broad spectrum of applications. FDTD is a simulator within Lumerical’s DEVICE Multiphysics Simulation Suite, the world’s first multiphysics suite purpose-built for photonics designers. The DEVICE Suite enables designers to accurately model components where the complex interaction of optical, electronic, and thermal phenomena is critical to performance. The Finite-Difference Time- Domain Method (FDTD) The Finite-Difference Time-Domain method (FDTD) is today’s one of the most popular technique for the solution of electromagnetic problems. The FDTD method makes approximations that force the solutions to be approximate, i.e., the method is inherently approximate. The results obtained from the FDTD method would be approximate even if we used computers that offered inﬁnite numeric precision. The inherent approximations in the FDTD method will be discussed in subsequent chapters. FDTD is a general and versatile technique that can deal with many types of problems. It can handle arbitrarily complex geometries and makes no assumptions about, for example, the direction of light propagation. It has no approximations other than the finite sized mesh and finite sized time step, therefore. noblehousehove.com_backend("torch") In general, the numpy backend is preferred for standard CPU calculations with “float64” precision. In general, float64 precision is always preferred over float32 for FDTD simulations, however, float32 might give a significant performance boost. The cuda backends are only available for computers with a GPU. The FDTD method makes approximations that force the solutions to be approximate, i.e., the method is inherently approximate.

Finally, the FDTD algorithm scales well with parallelization, so it is well suited to modern, multi-core and multi-processor computers as well as high performance computing HPC clusters.
Because FDTD is so versatile, it can address a wide range of applications. These include photonic crystals, plasmonics, CMOS image sensors, nanoparticle scattering and absorption, nano-patterned solar cells, OLEDS and LEDs, gratings, lithography, metamaterials and integrated optics, to name just a few.
You will notice that all of these applications involve wavelength scaled structure. Lumerical Support DEVICE Suite Lumerical University Videos FDTD - List of videos FDTD Algorithm - The FDTD Method FDTD This video is taken from the FDTD course on Lumerical University.
