Abstract

Transverse electromagnetic (TEM) transmission cells are used for exposing cell cultures to uniform TEM field and quantifying the biological effects. The uniformity of exposure is critical to quantifying the response versus dose of any observed biological effect. Standing waves and other electromagnetic field nonuniformities can lead to a nonuniform exposure. The finite-difference time-domain (FDTD) method provides an accurate means for quantifying electromagnetic field exposure levels within the culture cells. The specific absorption rate (SAR) can be calculated at each grid point within the cell culture given the FDTD-computed electric and magnetic field distribution throughout the TEM cell.
