摘要
本文论述了FD-TD法用于电磁辐射系统的近场计算问题,用该方法实现了对环形相控振子天线阵列的数字模拟。作为对方法的检验首先计算了单个振子天线上的电流分布,还计算了环中充满去离子水时阵列的近区场及其与人体躯干块状模型的相互作用。
The problems for calculating near-fields of EM radiation systems by using Finite Difference Time-Domain (FD-TD) method are discussed and the annular phased array of dipole antennas is simulated numerically by use of FD/TD method. For a test run the near-field and current distribution of the single dipole antenna are calculated. The near-field of the annular phased array of dipole antennas in central region filled with deionized water is computed and the interaction of near-field with a anatomically-based model of human torso is; considered as well.
