Efficient Frequency-Dependent Newmark-Beta-FDTD Method for Periodic Grating Calculation
In this paper, the Newmark-Beta algorithm is introduced into the finite-difference time-domain (FDTD) method in dispersion media, resulting in an unconditionally stable method for periodic metallic grating analysis. The proposed method eliminates the Courant–Friedrich–Levy cons...
