| Sumario: |
This exploratory paper discusses the simulation of the whole-body specific absorption rate (SAR) on electrically large bodies. By irradiating a spheroid by means of a plane wave, the relationship between the radiated electromagnetic fields and the internal fields generated in the object can be studied. The SAR could be calculated with conventional numerical methods up to 9 GHz with the computational power available. To overcome this limit, an approach using physical optics is proposed to extend the simulation range up to 100 GHz. Preliminary results obtained indicate that this could be a good alternative for high frequency simulations; however, the generalization of the method and further validation would be required as future work. |
