Methods to improve the uniformity of the millimeter‐wave (MMW) dose distribution on the cell monolayer in culture dishes are tested via experiments on MMW biological effects at the cellular level. Calculated using the finite‐difference time‐domain (FDTD) numerical technique, the MMW dose distribution, represented by the distribution of the MMW power density (PD) irradiated into cells and that of the MMW power absorption density (PAD) of cells, is analyzed for three culture dishes of different configurations. Results indicate that enlarging the culture dish diameter and reducing its bottom thickness are two effective methods to improve the MMW irradiation uniformity. © 2004 Wiley Periodicals, Inc.
