Excerpt from The Bell System Technical Journal, 1949, Vol. 28: A Journal Devoted to the Scientific and Engineering Aspects of Electrical CommunicationWhen the discriminant is much smaller than one, most of the energy can be carried in one line or component mode.When the discriminant is much larger than one, the energy ¿ow is nearly equally divided between the two lines or component modes. In wave guides of typical dimensions the coupling discriminant becomes one for a critical bending radius greater than a mile. For all sharper bends, that is for most practical installations, the discriminant is greater than one.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
