Meniscus Effect on the In Vitro Dosimetry of the T25 Flask Under 2.45 and 5.25 GHz Exposures

A practical technique is proposed to precisely model the meniscus of the cell culture in the standard T25 flask used in bioelectromagnetic experiments on RF exposure effects. In standard exposure scenarios, the numerical calculation with the meniscus model effectively improves the accuracy of the in vitro dosimetry, as compared to results from the conventional model with a flat liquid surface. The numerical study uses the finite-difference time-domain (FDTD) method incorporated with a conformal algorithm, which is examined for accuracy against the theoretical analysis.
