Description

Characterization of radioelectric environments. Regular spreading models have proved themselves effective to model problems where the wavelength is too long or short compared to the characteristic physical dimensions involved in the problem, such as curve radius, distances between the source and the obstacle, etc. For intermediate cases and multi-scale problems, hybrid models are used, which do not work so well. Nowadays, we work to improve the modelling of this kind of problems and to apply such models to positioning problems, description of sources, dosimetry and communications. The specific aim of this line is to create a network of measuring stations that, along with the use of personal dosimeters, allow to move forward in the problem of estimating the population exposure to the different types of signals emitted by the radio-communication services. On the one hand, we are working on a spreading model that allows to interpolate the results of the stations' measurements and, on the other hand, we are studying the interaction between the personal dosimeter and the body of the carrier, which alters the spreading patterns of the fields. In this case, simulation is used by finite differences in the time domain (FDTD) and the experimental verification of the results.
