Theory and Circuit Model for Lossy Coaxial Transmission Line
Abstract
The theory of signal propagation in lossy coaxial transmission lines is revisited and new approximate analytic formulas for the line impedance and attenuation are derived. The accuracy of these formulas from DC to 100 GHz is demonstrated by comparison to numerical solutions of the exact field equations. Based on this analysis, a new circuit model is described which accurately reproduces the line response over the entire frequency range. Circuit model calculations are in excellent agreement with the numerical and analytic results, and with finitedifferencetimedomain simulations which resolve the skindepths of the conducting walls.

MEASUREMENT OF THE DIRECTIVITY OF A COAXIAL DIRECTIONAL COUPLER BY USE OF A LENGTH OF PRECISION TRANSMISSION LINE
The quarterwave1ength line method of measuring the directivity of a coaxial coupler is described. It gives the error analysis of the method in detail and shows that the method has the capability of precise and repeatable measurements. (auth) 
Theory of magnetically insulated electron flows in coaxial pulsed power transmission lines
The Cartesian magnetically insulated transmission line (MITL) theory is extended to cylindrical coordinates. A set of equations that describe arbitrary electron flows in cylindrical coordinates is presented. These equations are used to derive a general theory for laminar magnetically insulated electron flows. The laminar theory allows one to specify the potentials, fields, and densities across a coaxial line undergoing explosive electron emission at the cathode. The theory is different from others available in cylindrical coordinates in that the canonical momentum and total energy for each electron may be nonzero across the electron sheath. A nonzero canonical momentum and total energymore » 
Applications of multiconductor transmission line theory to the prediction of cable coupling. Volume VI. A digital computer program for determining terminal currents induced in a multiconductor transmission line by an incident electromagnetic field. Phase report
The report describes a digital computer program which is designed to compute the terminal currents induced in a multiconductor transmission line by an incident electromagnetic field. Sinusoidal steady state behavior of the line is assumed. The transmission line is uniform and consists of n wires and a reference conductor immersed in a homogeneous, lossless, linear, isotropic medium. The n wires and the reference conductor are assumed to be lossless. The reference conductor may be a wire, an infinite ground plane or an overall, cylindrical shield. The incident electromagnetic field may be a uniform plane wave or a general nonuniform field.more »
