An application of the multilevel DG-FDTD to the study of a medical implant antenna in different body models

In this paper, we propose to use the multi-level DG-FDTD approach to analyze the evolution of the transmission coefficient between an implanted antenna in two different simplified body models (an homogeneous one and a three-layered one) and a 0.5lambda
₀
dipole in free space at various distances from the body model. The effectiveness of the multilevel DG-FDTD is compared to the classical DG-FDTD method.
