This paper represents the numerical analysis of Specific Absorption Rate (SAR) and temperature distribution within a real child head model exposed to mobile phone radiation at the frequency of f=900MHz. In this research the SAR and temperature distribution are obtained by numerical solutions of the equation of electromagnetic waves propagation and by bioheat equation, respectively, and are shown inside...
The subject of the paper is a comparative analysis of plate and grid electrode characteristic as an integral part of grounding system. Analysis was performed in term of resistances and potential distribution above the ground for both ground electrodes with the same dimensions and placed at the same depth. This research was carried out for vertically and horizontally installed electrodes. In order...
In this paper, the transient magnetic model of single-phase electromechanical meter using FEM is designed. Different power supply regimes of non-sinusoidal voltage and current waveforms were analysed with the considered impact of higher harmonics. Single-phase electromechanical electricity meters based on the principle of Ferraris energy meter for FEM application and as a source of measured data that...
It is well known that current having non-negligible value could appear in metal sheet of single-core power cables. This current causes additional heating of the cable and consequently, decreases the cable current capacity. Total current flowing through the metal sheet of the single-core cables consists of circulation, eddy and capacitive components. Circulation current depends on cable geometry, material...
The subject of this paper is monitoring of thermal effects on human head from mobile phones. In this paper temperature distribution and SAR at surface of human head close to source of electromagnetic radiation are shown. Results of simulation were compared with experimental results obtained with thermal imaging camera.
This paper presents the distribution of electric field inside a human head as well as around the electromagnetic field source, i.e. the mobile phone. Specific Absorption Rate (SAR), which is obtained inside a human head and the thermal effect due to exposure to electric field from mobile phone was presented. For this research two different models of human head have been used. In the first case electromagnetic...
