  A bio tissue model consisting of multilayer spherical cells including four
nested radial domains (nucleus, nuclear membrane, cytoplasm and plasma
membrane) is worked out to derive the cell heating dynamics in presence of
membrane capacitance dispersion under pulsed electromagnetic exposure. Two
possible cases of frequency-dependent membrana models are discussed: plasma and
nuclear membranes are dispersive, only the nuclear memebrane is dispersive . In
both models an high localized heating of the membranes occurs, without
significant temperature rise in the cytoplasm and nucleoplasm.
