We present simple parametric equations in terms of Jacobi elliptic functions that provide a realistic model of the shape of human normal erythrocytes as well as of variations in size (anisocytosis) and shape (poikilocytosis) thereof. We illustrate our results with parameterizations of microcytes, macrocytes and stomatocytes, and show the applicability of(More)
We calculate the turnover frequency spectra for erythrocyte hematic cells. For this purpose we present a simple approach to calculate the electric field induced torque on essentially dielectric objects. We define an effective dipole moment as a function of the cell internal electric field distribution which is determined by using an adaptive finite-element(More)
We study the influence of an external electromagnetic field of 1.8 GHz in the formation or disaggregation of long rouleau of identical erythrocyte cells. In particular we calculate the variation of the transmembrane potential of an individual erythrocyte illuminated by the external field due to the presence of the neighboring erythrocytes in the rouleau,(More)
This work presents a procedure to measure the effective dielectric permittivity in transmission lines. The procedure is based on an improved Frequency Domain Reflectometry (FDR) method. In this technique, the measured reflection coefficient as a function of the frequency is used to synthesize the response of a terminated transmission line to an ideal delta(More)
