Counterpoises for Transmission Lines
Transactions of the American Institute of Electrical Engineers, 1933Counterpoises are recommended for protecting electric power transmission lines against damage from lightning surges where other methods do not reduce the tower footing surge impedance to the desired level. In this paper a physical explanation of the theory of counterpoises is given together with an analytical solution of parallel counterpoise problems.

Flashovers on transmission lines
Electrical Engineering, 1936This paper is intended to be of practical use to transmission line engineers in that it shows how transmission line flashovers may be estimated and segregated into 1, 2, and 3 phase, and double circuit, flashovers. The method of calculation is comparatively simple and based upon analyses of statistical and analytical information.

Auditory perspective transmission lines
Electrical Engineering, 1934Describing methods whereby high quality sound reproduction in auditory perspective can be accomplished over long distances, this discussion centers largely upon a description of the exact technique employed in providing communication transmission circuits for the Philadelphia-Washington demonstration.

The Nonuniform Transmission Line
Proceedings of the IRE, 1932The problem of transmission of periodic waves along a transmission line, whose series impedance and shunt admittance per unit length very as any powers of the distance from some point, is solved. The solution is given in terms of Bessel functions. A length of such a line is considered as a four-terminal network, and the more important parameters of the

Transmission lines and transmission line resonators
2018Transmission lines are arrangements of conductors whose purpose is the transfer of power or information from a source to a load, both of which should be viewed as generic. That is, the source may well be a generator but it can equally be the output of a device such as a transmitter, a receiving antenna, or an amplifier, whereas the load can be any ...

Transactions of the American Institute of Electrical Engineers, 1945
SEVERAL general mathematical solutions have been published dealing with the tapered transmission line as applied to communication service. These solutions1–5 are in the form of a series or in Bessel functions, and are rather unwieldy for purposes of design.

The solution of transmission-line problems in the case of attenuating transmission line
Electrical Engineering, 1946COAXIAL LINES with solid dielectric often are used as feeders. Such lines have appreciable attenuation (of the order of 1.5 decibels per 100 feet at 100 megacycles per second). Application of standing-wave method of finding the receiving-end impedance, as based on the assumption of lossless transmission line, would introduce an appreciable error ...
