Abstract

The paper demonstrates the modelling of the interaction mechanism between the biological tissues and electromagnetic field at mobile communication frequency ranges. The implementing of modified FDTD numerical method using frequency scaled FDTD with Floquet periodic boundary conditions and modified PMLs, the microdosimetric modelling of bioelectro-magnetic interactions at cellular level, is established. In order to include the membrane effect on the biological tissues model in the analysis, the LE-FDTD is exploited to embed the lumped element cell-membrane model on the surface of the proposed tissue model in the FDTD computational domain. A new different structures of biological tissues are modeled and discussed, this includes a cluster of cylindrical cells. In order to imitate the effect of periodic replication of assemblages, Floquet periodic boundary conditions are imposed on the proposed model. Thus, the analysis of a large structure of cells is made more computationally efficient than the modeling of the entire structure. The total field distributions were shown in the context.
