PROPERTIES OF INTERCOUPLED TRANSMISSION LINES TERMINATED BY NEGATIVE RESISTANCE ELEMENTS WITH APPLICATIONS TO TUNNEL DIODE PULSE CIRCUITS

摘要

Transmission of nanosecond and subnanosecond pulse-coded information between successive processors can be accomplished only if the physical interconnection takes the form of a transmission line, terminated in its characteristic impedance, i.e., if reflectionless, distortion-free transmission between processors occurs. This fact is used as the basis for the investigation of intercoupled transmission lines. Differential matrix equations are developed from Maxwell's equations applied to multiconductor systems. The fact that wide¬band application is desired is used to -restrict the general solutions to expressions which permit the propagation of a single TEH mode only. It is shown that lossy intercoupled transmission line systems can be constructed with the property of distortion-free; single-mode propagation (generalized Heaviside systems). The specialization of this type of network to two intercoupled lines, which in turn are restricted by unidirectional propagation requirements, leads to the double-pair transformer.
