A model of two-component mass transfer in an inhomogeneous spherical system occurring in a nonlinear electromagnetic field is investigated. It is shown that the concentration in the inner region, at the boundary of the regions, as well as the concentration that crossed the border and got into the second region, depend on the nonlinearity parameter of the electrodynamic problem.</p>mass transferphase transitionnonlinear electrodynamic equationsheat and mass transferмассопереносфазовые переходнелинейные электродинамические уравнениятепломассообмен[Born M., Bhatia A.
