%X A spherical double shell model (SDM) for a single cell has been developed, using Laplace＊s equation in spherical coordinates and boundary conditions. Electric field intensities and dielectric constants of each region inside and outside of the cell have been estimated. The dielectrophoretic spectrum of the real part of a complex function (Re[f ( 肋)] were computed using Visual Foxpro Version 6, which gave calculated values pertaining to electrical properties of the cell model as compared with experimental values. The process was repeated until the error percentile was in an acceptable range. The calculated parameters were the dielectric constants and the conductivities of the inner cytoplasm ( 汍ic, 考ic), the outer cytoplasm ( 汍oc, 考oc), the inner membrane ( 汍im, 考im), the outer membrane ( 汍om, 考om), the suspending solution( 汍s, 考s) and the thickness of each layer (dom, doc, dim), respectively. This computer program provides estimated values of cell electrical properties with high accuracy and required minimal computational time.
