The numerical analysis of the electric field distribution behind the three-layer wall - POSTER

The paper presents the influence of building materials (aerated concrete, plaster board) on the electromagnetic wave propagation. The relation between structures of three-layer wall and electric parameters like electric permittivity building materials and aerated concrete conductivity are examined. It was observed that when changing the aerated concrete conductivity in the range s = 0¸0.015 S/m, the component of electric field (Ez) had higher values for permittivity εr’=2. However, when the conductivity value increased (above 0.02 S/m), the max(Ez) values were higher for εr’=2.45. The presented results give some information about field distribution around materials, which consist of some non-ideal, absorbing dielectrics. The finite-difference time-domain method (FDTD) was used. The delivered analysis may be useful for designers of wireless networks.
