Exact transparent boundary conditions for the parabolic wave equation are proposed. The dialectic permittivity depends linearly or quadratically on the coordinate. The integral kernels of these conditions contain only elementary functions. The conditions simplify numerical solution of the parabolic equation in open domains.
