چکیده
In this work, the influence of human body within the estimation of dosimetric values is analyzed. A simplified human body model, including the dispersive nature of material parameters of internal organs, skin, muscle, bones and other elements has been implemented. Such a model has been included within an indoor scenario in which an in-house 3D ray launching code has been applied to estimate received power levels within the complete scenario. The results enhance previous dosimetric estimations, while giving insight on influence of human body model in power level distribution and enabling to analyze the impact in the complete volume of the scenario.

Development of a free anthropomorphic voxel model of human body for wide-band computational electromagnetics dosimetry
To calculate and evaluate wave scattering and penetration of electromagnetic waves in different biological tissues it is necessary to use a realistic model of the human body, with all tissues resolved and separately assigned with appropriate electric/magnetic properties. We report the development of a realistic 3D whole-body human model that has been adapted for simulation in CST software, cont...

This paper presents our development of novel higher order electromagnetic (EM) modeling techniques for wireless technology applications based on the method of moments (MoM), finite element method (FEM), and physical optics (PO). Modern wireless systems involve electrically large EM structures (antennas, circuits, and components) that are very complex in both geometry and material composition. T...
متن کاملA Mixed FDTD-Integral Equation Approach for On-Site Safety Assessment in Complex Electromagnetic Environments
A mixed finite-difference time-domain (FDTD)-integral equation approach for the evaluation of the power deposition in the human body model immersed in a complex electromagnetic environment is proposed. The advantage of the proposed approach is that safety assessment for exposure to generic sources may be performed on-site, in a few minutes, with high accuracy and without the need of a high-powe...
