Computational microdosimetry at cellular level at millimeter wave frequencies
A microdosimetric study is performed on a canonical biological cell model in the 60-GHz band. Complex permittivity data of dielectric models of the membrane, cytoplasm, and extracellular medium at microwaves has been extrapolated to millimeter-wave (mmWave) frequencies. A quasi-static electromagnetic (EM) analysis is employed to solve the Laplace equation numerically. The results demonstrate that cellular and sub-cellular membranes are no longer able to shield the intracellular organelles at mmWave frequencies, as it is the case at lower frequencies, and almost 100% of the electric field penetrates inside the cell, reaching intracellular organelles.
