An oscillatory medium subject to external forcing at a frequency equal twice its natural frequency is studied in a regime where the nonvariational coefficients cannot be treated as small perturbations. We reveal numerically that domain walls can be stabilized to produce a moving stable domain and examine its stability against wavenumber instability. (C) 2000 Published by Elsevier Science B.V.
