Abstract :
In this paper, a numerical dosimetry scheme is proposed for pulsed high-power electromagnetic (HPEM) sources, which may induce biological effects such as “microwave hearing.” This auditory effect is linked to the specific absorption (SA) of biological tissue which is subject to regulatory limits. The presented simulation scheme using high-resolution human body phantoms takes into account the widespread spectral excitation range of pulse sources with the frequency dependency of dispersive biological tissue properties and of corresponding regulatory restrictions. Different examples of numerically computed and evaluated HPEM exposure scenarios are presented.
