Research of the Propagation Characteristic of Electromagnetic Wave in the Human Body

Abstract

This paper presents the propagation characteristics of sinusoidal wave that from an intestine-ingested in simple model of the human at the 403MHz and 923MHz, by using the finite-difference time-domain method through discrete Maxwell's equations. This simulation results exhibit the wave propagation process. These results can help us explain the phenomenon, the attenuation of the electromagnetic wave in human tissues is different due to dielectric property in various human tissues and different frequency that we choose. This results are useful for the design of wireless communications module of an ingestible device, e.g wireless capsule endoscope.
