Computational study of electromagnetic exposure of military personnel in a humvee

Electronic Attack (EA) antennas in the HF-VHF range are quite large. Thus, having large visual and radar signatures. An interesting approach to conceal those antennas is to evaluate the bottom side of the vehicle as a suitable antenna location. The output power of vehicular antennas used for EA can be a few hundred watts, therefore they produce strong electromagnetic radiation which can be dangerous for vehicle crew members. Electromagnetic (EM) exposure can provoke physiological and thermal effects, and has recently been considered as possibly carcinogenic. The Federal Communication Commission (FCC) has set limits of exposure to assure the safety of the general population against harmful EM exposure. Thus, it is of interest to research if the military personnel exposure inside military vehicles is not exceeding those limits, what are the advantages of a bottom location of the antenna versus more common locations and if there are other ways to enhance their protection.
