Analysis of millimeter-wave exposure on rabbit eye using a hybrid PMCHWT-MoM-FDTD method

In order to investigate thresholds of biological effects due to millimeter-wave (MMW) exposure, A hybrid method, which combines the Poggio-Miller-Chang-Harrington-Wu-Tsai method of moments (PMCHWT-MoM) and the finite-difference time-domain (FDTD) method, has been developed and applied to analysis of...

Zusammenfassung:	In order to investigate thresholds of biological effects due to millimeter-wave (MMW) exposure, A hybrid method, which combines the Poggio-Miller-Chang-Harrington-Wu-Tsai method of moments (PMCHWT-MoM) and the finite-difference time-domain (FDTD) method, has been developed and applied to analysis of millimeter-wave exposure on rabbit eye using dielectric lens antenna as an electromagnetic source. The PMCHWT MoM has been validated by comparison of calculated and measured electric fields radiated from the dielectric lens antenna. Then, the hybrid PMCHWT-MoM-FDTD method is used to determine specific absorption rate due to MMW exposure on rabbit eye, which was placed at the focal point of the antenna. It was found that the dielectric lens antenna with an input power of 10 mW produces a peak SAR of 86 W/kg in the eye cornea at 35 GHz.
