Analyses of several realistic exposure scenarios near cellular base stations

Abstract

This paper contains the results of computer simulations performed for several realistic scenarios of electromagnetic (EM) field evaluation near the cellular base station (CBS) and some analysis of obtained results. The motivation of this study is exposure assessment of EM energy on biological objects. There are scenarios of field distribution indoors, near the hill, obstacle like a wall and finally the field distribution inside the human body is computed. These scenarios are general and frequently encountering in practice inside space covered by wireless networks. Using the reasonable computational resources and keeping the accuracy of the solution acceptable for problems involving the electrically large objects the method of auxiliary sources (MAS) (R. Zaridze et al., 2002) (D. Kakulia et al., 2004) is used to simulate the EM field for the cases mentioned above
