TeV-scale gravity assumes that the true gravitational constant corresponds to the mass scale M¤ of the order of one or several TeV, at the expense of making gravity multidimensional. The weakness of the usual four-dimensional gravity results from the fact that only a small action of the gravitational lines of force is responsible for gravitational interaction in our world Which can be thought of as four-dimensional hypersurface (brane) in the D = n+4 dimensional bulk. The standard model particles live only on the brane, while the bulk is inhabited only by gravitons which participate in interactions with matter with equal strength. One of the strongest bounds on models of extra dimensions comes from SN1987A data, calculating extra energy losses due gravi-bremsstrahlung. Previous calculations of this process, however, didn't take into account plasma collective eects which is the goal of the present contribution. We use kinetic theory developed earlier to describe interaction of plasma with gravitational waves in 3+ 1 dimensions generalizing it to the ADD model. The perturbation theory is developed panding the solution in powers of the electromagnetic field E due to uctuations of the charged particles densities in the non-relativistic isotropic plasma.
