Research on Hybrid Algorithm of Explicit Newmark-FDTD and Traditional FDTD Methods
2021 International Applied Computational Electromagnetics Society (ACES-China) Symposium, 2021The Newmark method is used to discretize the subgridding numerical system, and explicit Newmark-FDTD method is obtained by employing the Neumann series to expand the inverse of the coefficient matrix. Furthermore, the hybrid algorithm of explicit Newmark-FDTD and traditional FDTD methods is employed to further improve the computational efficiency.

On the numerical properties of the ADI-FDTD and CNSS-FDTD method
Proceedings of the 12th IEEE Mediterranean Electrotechnical Conference (IEEE Cat. No.04CH37521), 2004The formula for the stability and numerical dispersion of the "alternating directions implicit" (ADI), finite-difference time domain (FDTD) and for the "Crank-Nicolson slit step" (CNSS) FDTD method are obtained and their properties are discussed.

On the accuracy of the ADI-FDTD method
IEEE Antennas and Wireless Propagation Letters, 2002We present an analytical study of the alternating-direction implicit finite-difference time-domain (ADI-FDTD) method for solving time-varying Maxwell's equations and compare its accuracy with that of the Crank-Nicolson (CN) and Yee FDTD schemes. The closed form of the truncation error is obtained for two and three dimensions.

On the Analytical Solution of the FDTD Method
IEEE Transactions on Microwave Theory and Techniques, 2016The finite-difference time-domain (FDTD) method is an effective and widely used time-domain method for solving electromagnetic problems. Conventionally, its solutions are obtained numerically in a march-on-in-time manner. In this paper, based on the eigenmatrix theory, we derive the analytical expression for the FDTD solution.

Applications of the DG-FDTD method
2nd European Conference on Antennas and Propagation (EuCAP 2007), 2007In this paper, we propose to use the dual-grid finite-difference time-domain (DG-FDTD) approach to analyze the characteristics of several antenna configurations. This method reduces the overall computational time and besides, it prevents from instabilities.

Slanted walls in the FDTD method
2005 IEEE Antennas and Propagation Society International Symposium, 2005In the finite-difference time-domain (FDTD) method, the spatial step is usually chosen to be between 5% and 12.5% of the minimal wavelength of interest. If the boundaries cannot be positioned at integer multiples of the chosen spatial step, one usually reduces the spatial step or uses a nonuniform grid.

Dispersion Analysis of the ADI-FDTD and S-FDTD Methods
2008Numerical dispersion performances of ADI-FDTD and S-FDTD methods have been compared. It has been shown that for time steps below the stability limits of the S-FDTD method it has Much better dispersion performance compared with the ADI-FDTD method and that the S-FDTD method can be usefully employed for space increments in the order of lambda/25 to ...

A multiwire formalism for the FDTD method
IEEE Transactions on Electromagnetic Compatibility, 2000The thin-wire formalism is a widely used subcell model that allows the finite-difference time-domain (FDTD) method to take account of wires thinner than the cell size. In this paper, the original formalism is generalized to a multiwire formalism that allows the FDTD method to take account of bundles composed of arbitrarily close wires.

A hybrid R-FDTD/FDTD algorithm using a method of subregion connection
2002 3rd International Conference on Microwave and Millimeter Wave Technology, 2002. Proceedings. ICMMT 2002., 2003As a recently developed technique for FDTD algorithm, R-FDTD leads to a memory-efficient formulation, with a direct memory reduction of 33% in the storage of the fields compared to traditional FDTD algorithm. However, R-FDTD is complicated to deal with the regions including conductors and source.
