摘　　要：采用电磁场时域有限差分法和二阶吸收边界条件 ,计算了 8毫米的毫米波辐射下培皿内细胞单层上细胞对毫米波的比吸收率 (SAR) ,从多个角度给出了SAR在培皿内细胞单层上的分布规律 ,分析了造成SAR不均匀分布的原因 ,提出了提高SAR分布均匀性的建议 。With finite difference time-domain (FDTD) method and the second order approximation of the absorbing boundary conditions (ABCs), the specific absorption rate (SAR) is evaluated for cells in the cell monolayer inside a culture dish under 8mm millimeter wave (MMW) irradiation. SAR distribution pattern over the cell monolayer in the culture dish is revealed in different phases, and the reason for the irregular SAR distribution is studied. Measures for improving the uniformity of SAR distribution is suggested and the result is valuable for designing experiments on MMW biological effects in the cellular level.
