Abstract：The idea about undulating propagation of electromagnetic wave is presented. And some characters and operating principle to form undulating propagation of electromagnetic wave by multifrequency radiation source with initial twisty phase angle continually varying versus the time are introduced. The electromagnetic wave propagation in the undulating pattern along the propagating path will profit many fields of the electromagnetic wave application, such as point to point communication, electromagnetic energy conveyance,detection and ranging etc.
