Pipelines for Electric Waves by H. E. M. Barlow Ph.D. M.I.E.E. ,
Pender Professor of Electrical Engineering,
University College, London
In the early days of the electric telegraph, a hundred years ago, and of the telephone, messages were sent from one place to another by two parallel wires. As the demand for these services increased it became necessary to use as the link not wires but coaxial cables capable of carrying a wide range of frequencies. But even these coaxial cables have now reached the limit of their capacity, and a new system is envisaged consisting of micro-waves guided along the inside of hollow metal tubes. These wave guides' are the subject of Professor Barlow's talk.
