magnetic), their characteristics (frequency, magnitude, orientation, etc.), and the size, shape, and electrical properties of the exposed body (human, animal). A biological body signifi-cantly perturbs an external electric field, and the exposure also results in an electric charge on the body surface.

ELF electric fields 4Just as a static electric field causes a charge to appear on the body’s surface, an oscillating ELF field will induce a charge that varies continuously and regularly in time 4In turn, this constant flow of surface charge will give rise to oscillating internal electric fields and currents 4However, these effects depend on.

In this paper, a thick-wire model of the human body exposed to the ELF electromagnetic field is presented. Unlike previous approaches which dealt with the conventional integral equation types (see, for example, [2], [6], [7], the proposed numerical modelling in this paper is based on the simplified frequency domain (FD) Pocklington integro-differential equation.

Two electric problems concerning the simple and complex models of human body are investigated in detail to study the accuracy, convergence and efficiency of ES-FEM. the human body being used by Japanese team [6,7]. The human body model is composed from nine parts (Dimensions are given in centimetres).

When considering the human exposure to high voltage and low intensity systems, such as overhead power lines, the electric fleld is dominant. The formulation is based on the quasi-static version of the.

To clarify the mechanism of the biological effects of ELF electric fields on a human body, we have investigated the physiological changes precisely caused by the local exposure of the field.
