Shielding of transmission lines
Electrical Engineering, 1941MODERN theories of direct-stroke protection premise that the ground wires are so located as to intercept the stroke and provide perfect shielding. In spite of the fundamental importance of this question there still exists considerable doubt as to the correct position of the ground wires relative to the transmission conductors.

Overvoltages on transmission lines
Electrical Engineering, 1934Observations of line-to-ground voltages have been made under routine operating conditions on an isolated neutral system, a Petersen coil system, 3 neutral resistance grounded systems, and 2 directly grounded systems. Results of these observations are given in this paper.

Resonances for Microstrip Transmission Lines
SIAM Journal on Applied Mathematics, 2004Summary: We rigorously derive asymptotic formulae for resonances associated with a microstrip transmission line mounted on a planar waveguide with variable electromagnetic characteristics when the width of the line goes to zero.

There is great need for a better understanding on the part of transmission engineers of the traveling waves on lines. The complete analysis of such waves is inherently complicated, but there are certain approximate relations by which the progress of waves on our ordinary systems may be readily studied.

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.
