The biconjugate-gradient fast-Fourier-transform (BCG-FFT) method and the finite difference time-domain (FDTD) method are both capable of solving the 3-D human head absorption problem. However, the choice of methods depend on its applications. The FD-TD method is a time-domain method used to solve Maxwell's curl equations by replacing partial derivatives with finite difference approximations. The BCG-FFT method is a frequency domain iterative method used to solve the integrodifferential equation resulting from convolving equivalent sources with the dyadic Green's function. The FD-TD method is efficient for high frequency calculations while the BCG-FFT method is efficient for low frequency applications.
