Title: APPARATUS AND METHODS FOR LAUNCHING ELECTROMAGNETIC WAVES HAVING A CERTAIN ELECTRIC FIELD STRUCTURE
Abstract:
Aspects of the subject disclosure may include, receiving a signal, and launching, according to the signal, an electromagnetic wave along a transmission medium, where the electromagnetic wave propagates along the transmission medium without requiring an electrical return path, and where the electromagnetic wave has a phase delay profile that is dependent on an azimuth angle about an axis of the transmission medium. Other embodiments are disclosed.
