Abstract: 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 buman torso is considered as well. -
