20) 43 The FDTD Method The fourth-order staggered difference achieves much lower numerical dispersion compared to the second-order staggered difference and shows potential advantages in large-scale electromagnetic simulations. The main pitfalls of the method involve low stability and difficult treatments of inhomogeneous boundaries. The former can be improved by introducing the R-K method or the symplectic integration scheme. The latter can be improved by recently developed high-order conformal and subgridding techniques [14,26–29].
This computational cost motivates research for a more efficient sensitivity estimation approach. The algorithm presented in  aims at efficiently estimating the objective function gradient with the FDTD method. 12) where J, ε, σ, and μ are the electric current density, permittivity, conductivity, and permeability, respectively. 13) where Ė and Ë are the first and second time derivatives of the electric field components, respectively. M, N, and K are the symmetric system matrices, and Q is the excitation vector.
