Computer simulation study of the penetration of pulsed 30, 60 and 90 GHz radiation into the human ear.

ABSTRACT: There is increasing interest in applications which use the 30 to 90 GHz frequency range, including automotive radar, 5 G cellular networks and wireless local area links. This study investigated pulsed 30-90 GHz radiation penetration into the human ear canal and tympanic membrane using computational phantoms. Modelling involved 100 ps and 20 ps pulsed excitation at three angles: direct (orthogonal), 30° anterior, and 45° superior to the ear canal. The incident power flux density (PD) estimation was normalised to the International Commission on Non-Ionizing Radiation Protection (1998) standard for general population exposure of 10 Wm^-2 and occupational exposure of 50 Wm^-2. The PD, specific absorption rate (SAR) and temperature rise within the tympanic membrane was highl
