An application of the multi-level DG-FDTD to the analysis of the transmission between a dipole in free-space and an implanted antenna in a simplified body model with various positions

We propose to use the advantages of the multi-level dual-grid finite-difference time-domain (DG-FDTD) method to determine, in a short computation time, the transmission between an antenna implanted in a simplified homogeneous body model and a half-wavelength dipole (at 402 MHz) located in free space. The transmission coefficient is determined for four different positions of the body.
