Abstract:

Influence of the culture dish configuration on the millimeter‐wave (MMW) irradiation distribution on the cell monolayer is analyzed for related bioelectromagnetic experiments. The MMW power density (PD), power absorption density (PAD) and specific absorption rate (SAR) are calculated with the finite‐difference time‐domain (FDTD) numerical technique and their distributions over the cell monolayer are displayed for the circular, square and combined culture dishes. As descriptions of the MMW irradiation uniformity on the cell monolayer, the mean, standard deviation (SD) and relative standard deviation (RSD) of the distributions are studied. Culture dishes of different configurations are recommended in different cases according to the radius of the cell monolayer to improve the irradiation uniformity since the influence of their configurations on the MMW irradiation distribution is significant.

Keywords: cell monolayer; millimeter wave irradiation; power absorption density; power density; specific absorption rate
