Currents induced in an anatomically based model of a human for exposure to vertically polarized electromagnetic pulses

Dipole models for the far-field representation of EMP simulators with application to estimates of human RF exposure

“…The average energy per molecule (normalized to kT) is at least eight orders of magnitude (depending on the distance ffomthesource)below therandomthermalenergyatatempeof 293 Kelvin. Calculations with detailed FDTD models of the human body [8] show that specific absorption for organs within the body can be considerably larger or smaller than whole body absorption. For example, Table I1 of reference 8 lists specific absorption in the ankle as a factor of almost U) larger than whole body absorption.…”

Currents induced in the human body for exposure to ultrawideband electromagnetic pulses

“…The procedure to obtain the anatomically based model of the human body is detailed in our earlier publication [1]. Briefly, we used anatomical sectional diagrams of the human body that were available in the book by Eycleshymer and Schoemaker [6].…”

Some bioelectromagnetics research at the University of Utah: Acceptance speech on the occasion of receiving the d'Arsonval medal

“…To obtain the biometrically correct height and weight of 175.5 cm and 69.6 kg for the "average" man, we had to increase the cell size slightly to 1.3 1 and 2.62 cm for the two models, respectively. These models representing the human body (45,024 and 4,528 cells, respectively) were then used for a number of applications involving whole-body or partial-body exposures to spatially uniform or nonuniform (far-field or near-field), sinusoidally varying electromagnetic fields or pulses [Chen and Gandhi, 1991;Gandhi, 19901. With increased computer memory and improved efficiency of the numerical codes, it is now possible to obtain SAR distributions for coupled parts of the body represented by 1,000,000-5,000,000 cells. Therefore, higher resolution models with cell sizes on the order of millimeters have been developed both in our laboratory and elsewhere [see, e.g., Dimbylow, 19931.…”
