Numerical dosimetry for cells cultured in Petri dishes exposed to a six-degree- freedom millimeter-wave radiator

A numerical dosimetry is performed for experiments studying effects on cornea cells cultured in Petri dishes exposed to 50 GHz millimeter wave (MMW). An algorithm is developed to calculate the incident field from a six-degree-freedom MMW radiator, with respect to its specified position and orientation. With the algorithm, the finite-difference time-domain (FDTD) method simulated the interaction between the incident MMW and the Petri dishes. The specific absorption rate (SAR) in cells and the homogeneity of the SAR distribution are calculated and analyzed for dosimetric assessment in related MMW experiments on cells in vitro.
