✦ Synopsis

w x 10 simulation results. The excellent agreement between FDTD and analytical or MMP results observed in these two simulations gives confidence that the FDTD method can accurately model curved absorbing objects for near-field simulations.

IV. CONCLUSIONS

The FDTD method has been demonstrated to give excellent comparisons with analytical, measured, and MMP results for the fields or SARs within planar and spherical absorbing tissue phantoms very near dipole antenna sources for parameters approximately representing cellular telephone simulations. The excellent agreement obtained validates the FDTD method for near-field simulations. Additional work is ongoing in our laboratory to assess the accuracy of the FDTD method for more complicated sources such as realistic cellular telew x phones 11, 12 by comparing calculated near-field SARs and far-field radiation patterns with measurements.
