Applications of the DG-FDTD method
Résumé
In 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. It has been applied to the analysis of far-field and impedance characteristics of an integrated lens antenna and of a MIMO array. A dosimetry problem for phone / head interaction is also presented in the paper.
