The Electric Field Calculation for Mobile Communication Coverage in Buildings and Indoor Areas by Using the Method of Auxiliary Sources

“…In order to find the field distribution in the rooms, a very efficient method called Method of Auxiliary Source is preferred. Approximately for 50 years, MAS is used in the diffraction problems by different researchers including 2-and 3-dimensional problems [8][9][10][11]. e method also gives the ability to find the near field distributions.…”

“…e main advantage of MAS is to locate the specifically arranged auxiliary sources on two imaginary surfaces which are above and below the real surface of the object. In this way, the singularity problem while applying boundary conditions is avoided [8][9][10][11]. e imaginary surface locating interior of the obstacle stands for the scattered field outside the obstacle by applying the boundary condition on the real surface, whereas the imaginary surface locating exterior of the obstacle stands for the scattered field inside the obstacle by applying the boundary condition on the real surface.…”

“…e number of collocation points depends on the frequency. e investigation shows that, in order to get the correct solution, for each λ 2 , there should be at least 9 points, where λ is the wavelength in the dielectric [8][9][10]. Dielectric permittivity and conductivity are ε � 4, σ � 0.05 S/m [12].…”

“…Full-wave simulation is a better approximation to the real scenario. In previous works [8,9], the case of the human body located in the metallic room with transparency was investigated. On the contrary, the study carried out in this paper takes into account the wall as the lossy dielectric medium.…”
