The numerical analysis of the influence conductivity of clinker bricks and the size of their hollows on the distribution of the electromagnetic field

The aim of this article is to present the analysis of the effects connected with the propagation of electromagnetic waves within an area containing non-ideal, non-homogenous and absorbing dielectric. The presented situation is one of the distribution of electromagnetic field generated by a wireless communication system operating within the standard frequency (f=2.4GHz). The analysis included single and double layered walls used in housing construction, built from hollow clay bricks with different amounts of holes. The results were then compared with identical versions of walls built from solid brick. The influence of the size of holes, the contained clay mass percentage and its conductivity on the distribution of electromagnetic field was discussed.
