Webwhere σ j is the conductivity of species j, m Bruggeman factor considering the effects of tortuous conduction paths and constricted contact areas between particles. The electric potential loss inside the interconnect plate is assumed to be negligible due to the high conductivity of the metallic material. It is supposed here that the time dependence of the electromagnetic field is given by the factor (). In this paper Bruggeman's approach was used, but electromagnetic field for electric-dipole oscillation mode inside the picked particle was computed without applying quasi-static approximation.
