An Off-Center “Coaxial” Cable
نویسندگان
چکیده
A “coaxial” transmission line has inner conductor of radius a and outer conductor of radius b, but the axes of these two cylinders are offset by a small distance δ ¿ b. Deduce the capacitance and inductance per unit length, and the impedance Z, accurate to order δ/b. The (relative) dielectric constant and permeability of the medium between the two conductors both unity. The relevant frequencies and conductivities are so large that the skin depth is small compared to δ.

Experimental Characterisation of Coaxial Sleeve Baluns for Handset Measurements
A broadband method for measurement of devices for counteracting cable effects is proposed. A magnetic dipole source is emulated by an electrically small shielded-loop probe next to a coaxial cable. Measurement results for a typical 890 MHz coaxial sleeve balun are presented.
متن کاملLightning-induced currents in buried coaxial cables: A frequency- domain approach and its validation using rocket-triggered lightning
The aim of this paper is to present an experimental validation of a frequency-domain approach to the solution of the lightning electromagnetic field-to-buried cable coupling equations. The coupling to the inner conductor is evaluated using the concept of cable transfer impedance. The theoretical model and relevant computer code are tested using experimental data on lightning-induced currents in...

متن کاملHigh Voltage Pulse Generator by connecting Normal Coaxial Cable in series and in parallel without using Blumlein method
In order to carry out the simulation of the electrical noise, a pulse generator with fast rise time is needed. For this reason, the pulse generator using a coaxial cable is usually used. The pulse generator consists of a DC power supply, a charging resistor, a coaxial cable, a relay, and a terminator. Even the same voltage as charge voltage was outputted when the termination of the impedance wa...
