A hybrid method of FDTD(2,4) and subgrid FDTD(2,2) for modeling of coupling

IEEE Antennas and Propagation Society International Symposium (IEEE Cat. No.02CH37313), 2003
With recent technological advancements, antenna elements have become smaller whereas the platforms they operate on, e.g., helicopter airframes, become electrically larger. These problems yield large computational domains and require significant computational resources.

Antenna Q-factor computation with FDTD method

11th International Symposium on Antenna Technology and Applied Electromagnetics [ANTEM 2005], 2005
In 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.

Pointwise radiator in FDTD method

2010 5th International Confernce on Ultrawideband and Ultrashort Impulse Signals, 2010
The veracity of numerical FDTD simulation depends on a large extent on correct realization of the EM field source in the computation scheme. A survey of physical correspondence, simplicity of realization and convergence for several basic types of sources, being widespread in literature on FDTD simulation, is presented in the work.

Introduction to the Parallel FDTD Method

2013
The finite-difference time domain (FDTD) method is a numerical technique based on the finite difference concept. It is employed to solve Maxwell's equations for the electric and magnetic field distributions in both the time and spatial domains. The FDTD method utilizes the central difference approximation to discretize two of Maxwell's curl equations ...

A Huygens Subgridding for the FDTD Method

IEEE Transactions on Antennas and Propagation, 2006
A new subgridding technique is presented for the finite-difference time-domain (FDTD) method. The connection between the grid and the subgrid is realized by means of equivalent currents. The ratio of the steps of the grids can be arbitrarily large, and no significant reflection is produced from the grids interface.
