Electromagnetic simulation of specific absorption rate at 5G frequencies with a simplified human head model and a multi-solver method

An electromagnetic modeling approach is presented for the simulation of the specific absorption rate (SAR) in a human head at 60 GHz. Based on the strong skin effect, the human head model is simplified to reduce the computation cost. The multi-solver method based on the Robin transmission condition is employed to compute electromagnetic fields in the simplified human head. The SAR is calculated after the electromagnetic fields are computed. Numerical examples show that the multi-solver method is very efficient in solving electromagnetic fields in the human head and the simplified human head model can be used in the SAR simulation with an acceptable accuracy.
