The aim of the article is to analyze the influence of the variability of the electrical parameters of non-ideal and absorbing dielectric (usual concrete) on the values of the electric field intensity. A detailed analysis was also made of the influence of the reinforcement diameter, the number of rows and the spacing between the bars on the values of the electric field intensity. The subject of the research was a model containing a loadbearing wall made of concrete (absorbing dielectric) with reinforcement in the form of steel rods (conductor). Four reinforcement systems commonly used in construction were analyzed. Additionally, the discussion covered the influence of electrical parameters (electric permittivity, conductivity) on the field intensity values calculated for heterogeneous, complex material structures. The results of the field generated by the wireless communication system operating at the frequency f = 5 GHz are presented. The numerical finite difference time domain (FDTD) method was used. The influence of the values of electric permittivity and conductivity of concrete on the field intensity values was discussed in detail.

Celem publikacji jest analiza wpływu zmienności wartości parametrów elektrycznych nieidealnego i absorbującego dielektryka (beton zwykły) na wartości natężenia pola elektrycznego. Również dokonano szczegółowej analizy wpływu średnicy zbrojenia, liczby rzędów oraz rozstawu pomiędzy prętami na wartości natężenia pola elektrycznego. Przedmiotem badań był model zawierający ścianę nośną wykonaną z betonu (absorbujący dielektryk) wraz ze zbrojeniem w postaci stalowych prętów (przewodnik). Analizowano cztery, powszechnie stosowane w budownictwie układy zbrojenia. Dodatkowo dyskusji poddano wpływ parametrów elektrycznych (przenikalność elektryczna, konduktywność) na wartości natężenia pola obliczone dla niejednorodnych, złożonych struktur materiałowych. Zaprezentowane zostały wyniki pola generowanego przez system komunikacji bezprzewodowej pracujący przy częstotliwości f=5 GHz. Zastosowano numeryczną metodę różnic skończonych w dziedzinie czasu (FDTD). Szczegółowo omówiono wpływ stosowanych w literaturze wartości przenikalności elektrycznych oraz konduktywności betonu na wartości natężenia pola.
