Abstract

This paper demonstrates the detailed electromagnetic modelling of biological cell structures by using modified subgridding FDTD techniques. This is done by incorporating a quasi-static FDTD solution, Floquet periodic boundary conditions and modified PML boundary conditions to achieve microdosimetric modelling of bioelectromagnetic interactions at cellular level. Particular attention is paid to exploration of the field distribution over the membrane layer of the biological cells. The method enables the analysis of a large structure of cells in a more computationally efficient way than the modelling of the entire structure. An example is given to prove the stability of the proposed subgridding FDTD. The total fields of the simulated structures are shown to give reasonable and stable results at 2450MHz.
