In this paper, the Specific Absorption Rate (SAR) and temperature distribution in a human head model with a Deep Brain Stimulation (DBS) implant are numerically analyzed. Research on the electromagnetic exposure of DBS patients remains limited. A realistic three-dimensional human head model comprising skin, fat, bone, and brain tissues, along with a DBS implant, is exposed to a dipole antenna operating at 900 and 1800 MHz with a radiated power of 0.125 W. A coupled electromagnetic wave propagation and bio-heat transfer problem is solved using the Finite Element Method (FEM). The SAR and temperature distributions in different head tissues are evaluated. The simulation results show that the maximum SAR (2.57 W/kg) occurs at 900 MHz, while the maximum temperature (37.60 °C) is observed at 1800 MHz. At both frequencies, the SAR values in the tissues exceed the International Commission on Non-Ionizing Radiation Protection (ICNIRP) limit of 2 W/kg; however, the corresponding temperature increase remains within the permissible safety threshold.

摘要

In this paper, the Specific Absorption Rate (SAR) and temperature distribution in a human head model with a Deep Brain Stimulation (DBS) implant are numerically analyzed. Research on the electromagnetic exposure of DBS patients remains limited. A realistic three-dimensional human head model comprising skin, fat, bone, and brain tissues, along with a DBS implant, is exposed to a dipole antenna operating at 900 and 1800 MHz with a radiated power of 0.125 W. A coupled electromagnetic wave propagation and bio-heat transfer problem is solved using the Finite Element Method (FEM). The SAR and temperature distributions in different head tissues are evaluated. The simulation results show that the maximum SAR (2.57 W/kg) occurs at 900 MHz, while the maximum temperature (37.60 °C) is observed at 1800 MHz. At both frequencies, the SAR values in the tissues exceed the International Commission on Non-Ionizing Radiation Protection (ICNIRP) limit of 2 W/kg; however, the corresponding temperature increase remains within the permissible safety threshold.
