The update equations of the FDTD algorithm Finite-Difference Time-Domain Method in Photonics and Nanophotonics 23 for the adjoint problem are the same as those of the original simulation if we solve for (–λ, λH). Therefore, the same absorbing boundary conditions are used in both simulations, which simplify the implementation and allow for using the commercial tools. 1 AVM Approach for Dielectric Discontinuities Since most of the photonic devices are dielectric-based structures, in this section we show how the AVM approach can be adapted to dielectric discontinuities.

Characterizing unique features, exploring new functionalities, and optimizing performances of nanostructures and nanodevices strongly depend on the rigorous solution of Maxwell’s equations. As an accurate, fast, and efficient full-wave solver, the FDTD method can help to predict electromagnetic responses, understand working principles, reduce experimental costs, and shorten development periods of nano-optical designs. On one hand, the random, multilayered, and periodic nanostructures of interest have the inhomogeneous, dispersive, and anisotropic characteristics, presenting many challenges in developing the FDTD method.
