Title: Analysis of the influence of the conductivity of bricks, type of bricks and size of the hollows on the values of the electric field intensity
Abstract: The aim of the publication is to analyse the influence of brick walls used in single-family housing on the values of the electric field intensity. Three types of bricks from which the wall was made were considered (solid brick, brick with 18 hollows and brick with 30 hollows). The analysis also took into account the impact of the size of the hollows on the field values and the variability of the conductivity of the brick. The results were compared for the arrangement with an asymmetric arrangement of bricks with a symmetrical arrangement, which may correspond to walls made of hollow bricks. The analysis concerned the frequency used in wireless communication (Wi-Fi), i.e. f=2.4 GHz. The influence of the size of the structural clay tile and the conductivity of bricks on the electric field values is discussed. A method based on Maxwells equations (Finite Difference Time Domain Method), was used for the analysis.
Key words: electromagnetic waves propagation, finite difference time domain method (FDTD), wireless communication, building materials.
