Abstract :
The lack of adequate techniques for measuring the specific absorption rate (SAR) of microwave energy in such lossy structures as biological bodies is pointed out. A non-invasive method, based on the use of an array of small, non-perturbing electric field probes, is proposed. The feasibility of the method is demonstrated, using a circular cylindrical model of the human body. The simplifying assumptions on the nature of the incident signal are discussed
