Abstract: An analysis is made of the millimeter-wave(MMW) dosimetry in culture dishes used in experiments on MMW biological effects at the cellular level. The finite-difference time-domain(FDTD) technique is employed to compute the MMW power density(PD) irradiated into cells in two culture dishes with typical configurations and the MMW specific absorption rate(SAR) of cells with consideration of the 8mm wavelength. A qualitative analysis as well as quantitative illustrations is carried out for the outcomes. As indicated in the results, distributions of the MMW PD irradiated into cells, the SAR of cells, and experimental results are significantly influenced by culture dish configurations which should be seriously considered in related experiments.

Key words: culture dish, millimeter wave, dosimetry, FDTD technique
