It is shown experimentally that, by analogy with a narrow channel and high-frequency phase-slip centers (ac PSC), high-frequency phase-slip lines (ac PSL) arise in a wide superconducting film irradiated with an external microwave field whose power exceeds a critical value . For a dc probe current much weaker than the critical current, such a state is found to be resistive; this manifests as linear initial sections of the current-voltage characteristics (IVCs), reflecting the voltage drop on ac PSL. It is shown that for monotonically varying power of the electromagnetic irradiation field the slope of the linear sections of the IVCs changes discretely and is a multiple of the resistance of an ac PSL which arises at power .
