The paper deals with the three dimensional modelling of the human body exposed to extremely low frequency (ELF) high voltage electric fields by mean of the boundary element method (BEM). Numerical results along head, neck, torso, abdomen, arms, legs and ankles are presented and discussed in the case of grounded subject standing under power distribution lines. The objective is to characterise the influence...
The paper introduces a multi-element model of man exposed to a radiation field for evaluating the local specific absorption rate (SAR) distributions. Use will be made of an assembly of constitutive elements representing a postured human subject. Based on the SAR dependence on frequency, two different equivalents of the exposed human body are proposed. For frequencies below human resonance, the irradiated...
Thermal analysis of human exposure to base station antennas radiation is presented in this article. The formulation is based on complex anatomic homogenous model of human body. The temperature rise is determined by solving the Pennes bio-heat equation using the standard finite element method, and it is found rather negligible. The advantage of the presented model is that it is fully anatomic
The goal of this paper is to investigate interaction between electrostatic field of video display units (VDU's) and human head in front of it. Special attention is given to the field at the surface of the face. The finite element model for assessment of the electrostatic field, by solving Laplace equation for the electric potential, is implemented. The electrostatic field is calculated for two different...
Analytical model of human body is used to calculate the electric field and current density induced in human body when it is exposed to high frequency electromagnetic fields (50-200 MHz). Especially, of interest are frequencies used by radio amateurs (50-200 MHz). Formulas used in this study are derived by using a cylindrical model of human body. Tabulations and graphical representations illuminate...
This paper presents the measurements of the electromagnetic fields present in the student microwave laboratory. Due to the high altitude and vulnerability to the ambient electromagnetic fields, it was interesting to see if the level of exposure to microwave frequencies in the laboratory exceeds the international and Croatian standards. The measurements were done in the frequency range from 75 MHz...
