Numerical Analysis of the Building Materials Electrical Properties Influence on the Electric Field Intensity

Abstract

The paper discusses the numerical analysis of the electromagnetic waves propagation effects within an area containing a non-ideal, non-homogenous and absorbing dielectric. The relation between homogeneous and heterogeneous structures of building materials and electric conductivity are examined. Different ranges of the conductivity were analyzed at frequency 2.4 GHz with respect to commonly used materials like the concrete, aerated concrete, solid brick and brick with holes. The analysis was performed using the FDTD method. The obtained values of the electric field intensity provide the determination of an attenuation coefficient for the different walls constructions. The detailed analysis of the different buildings constructions will make possible better understanding of the wave phenomena as well as counteract a local signal fading at planning of the wireless networks systems.
