The analysis of human head interaction with a hand-held mobile using the non-uniform FDTD

Recent years have seen an explosive growth in the area of wireless communication and, around the world, several hundred millions of subscribers are expected to have mobile phones by the year 2000. With the proliferation of these phones, questions have arisen about the interaction of the electromagnetic field with biological tissues in general, and about the power absorbed by the human head in particular. In this paper we employ efficient numerical techniques to compute the local absorbed power in the head and to predict the modification of the antenna performance due to its close coupling with the head.
