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.

Antenna Q-factor computation with FDTD method
11th International Symposium on Antenna Technology and Applied Electromagnetics [ANTEM 2005], 2005In this work, we have developed a new method for the calculation of the antenna quality factor by using the numerical method FDTD. The results obtained with our method are compared with the analytical approach of McLean and Geyi. The results show good agreement between FDTD and Geyi formulation.

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 TLM-FDTD method for the modelling of diffusion
International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, 2000Summary: A new hybrid TLM-FDTD algorithm for solving diffusion problems is described. The method utilizes the transmission line model to define the time step and the FDTD's leap-frog algorithm to determine the voltages and currents of the network analogue of the diffusion equation.

MODAL ABSORPTION IN THE FDTD METHOD: A CRITICAL REVIEW
International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, 1997This paper deals with absorbing boundary conditions for the finite difference time domain (FDTD) method applied to homogeneous lossless waveguide structures. A theoretical formulation of the so-called ‘modal absorption’ (MA) is developed. On the basis of this theory different implementations available in the literature have been derived and compared ...

Several high accuracy finite-difference time-domain (FDTD) methods have been developed to overcome the phase velocity errors present in the FDTD method. The nonstandard FDTD method has been developed as one of those. The phase velocity errors of the method are investigated and the characteristics are compared with other high-accuracy FDTD methods. As a
