A 3-D body model for physical activity monitoring by microwave radiation

The human body is a very complex structure, which has not been studied explicitly, until today, for remote monitoring application or wireless communication. This paper presents a preliminary study in the will to demonstrate how the combination of primitive shapes such as spheres, cylinders and parallelepipeds allows creating a simplified 3-D body model sufficient to analyze the interaction mechanisms of electromagnetic waves and resulting more efficient than numerical tools in terms of computational requirements. A comparison between the electric field scattered from a simple geometrical shape and from the realistic face of a phantom will be presented to show the accuracy of the model. To conclude, some experimental results with simulated data will be compared in order to provide a preliminary validation of the method.
