Abstract

A method and system for communicating information between subscribers over power transmission lines which normally convey electrical power to a plurality of diverse electrical sites for providing electrical power to electrical devices disposed at these diverse electrical sites. The subscribers on the communication network are located at these electrical sites. The electrical power conveyed over the power transmission lines is in the form of electromagnetic radiation which has an electrical field component and an associated magnetic field component. The information, such as telephonic voice communication or other data, is transmitted in the magnetic field component of the electromagnetic radiation carried over the power transmission line, such as by exciting the field with a MASER, in order to enable communication between the subscribers at the various electrical sites. The MASER provides an inverted atomic population by pumping directly, through a Q-switch and a synthetic aperture lens, into the atomic population of the electromagnetic wave carried over the power transmission line to produce acoustic wave oscillation at the appropriate atomic transition frequency. The MASER output is transmitted within the existing magnetic flux envelope created by the magnetic field of the electromagnetic radiation carried over the power transmission line and the power transmission line acts as a magnetic waveguide for the coherent magnetic frame emissions from the MASER. Inductive coupling is used to receive the transmitted information.
