The low temperature transverse dielectric function is found for Josephson-coupled layered superconductors for polarization of an electric field perpendicular to the layers in the presence of a dc magnetic field oriented parallel and perpendicular to the layers. The plasma edge lays well below the superconducting gap in highly anisotropic systems and it is reduced to zero in strong parallel fields due to the overlap of nonlinear regions of Josephson vortices. In strong perpendicular fields the plasma edge is also reduced due to displacements of pancake vortices from straight lines caused by pinning centers. Corresponding characteristic fields for plasma edge reduction are found.
