An Artificial Anisotropy Four-Step HIE-FDTD Method With Lower Numerical Dispersion Error
IEEE Access, 2020 In this article, by introducing artificial anisotropic (AA) parameters in the four-step hybrid implicit-explicit finite-difference time domain (HIE-FDTD) method, an AA four-step HIE-FDTD method is proposed, which can reduce the numerical dispersion error

Experimental investigation of the energy backflow in the tight focal spot
Компьютерная оптика, 2020 Using two identical microobjectives with a numerical aperture NA = 0.95, we experimentally demonstrate that the on-axis intensity near the tight focal spot of an optical vortex with a topological charge 2 is zero for right-handed circular polarization ...

Error between unconditionally stable FDTD methods and conventional FDTD method
Electronics Letters, 2006 Both the ADI-FDTD method and the CN-FDTD method can be viewed as approximate factorisation of the conventional FDTD scheme, so the error between these methods and the conventional FDTD method is obtained. It is shown that the error is associated with the time step size, the permittivity and the permeability of the medium, and the spatial variation rate

Rotated Subgrids in the FDTD Method [PDF]
IEEE Transactions on Antennas and Propagation, 2016 Although the finite-difference time-domain (FDTD) method is well established for addressing a wide variety of problems, a long standing challenge is to reduce discretization errors while avoiding the use of impractically large numbers of cells, particularly when the structure is large and contains regions of fine detail. One solution is to use subgrids,
