| Abstract: | In this paper,the MRI geometry-electromagnetic human body model for simulating handset EM radiation with finite-difference-time-domain(FDTD) was built in the foundation of medical anatomy technology.The interaction between handset monopole and helical antennas and anatomically realistic human body model was discussed at frequency 900MHz.The feasibility of this method was proved through comparing with measured values.The effects on antenna's radiation characteristics due to the presence of human body were also analyzed. |
