An Off-Center “Coaxial” Cable
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...
متن کامل“Hidden” Momentum in a Coaxial Cable
Calculate the electromagnetic momentum and identify the “hidden” mechanical momentum in a coaxial cable of length L, inner radius a, outer radius b, when a battery of voltage V is connected to one end and a load resistor R0 is connected to the other. The current may be taken as uniformly distributed over the inner conductor, which has resistivity ρ. The outer conductor has negligible resistivit...
متن کاملPassive Sensing Node Network for Monitoring Performance of RF Connector-Coaxial Cable System
A passive sensing node technology is introduced for monitoring the integrity of RF coaxial transmission lines and associated RF connectors in the UHF range of frequencies. Each passive sensing node is powered by a transmission line coupler inside the coaxial cable. Passive sensing node sensing elements, fineline interconnect metallurgy, transmission line coupler, and electronics are packaged on...
متن کاملCellular remote antenna feeding: Optical fibre or coaxial cable?
Introduction: It has been shown by Jung and Tonguz [1] that uplinks in personal communication system networks can be built using coaxial cable for link lengths < 0.6 – 1.4km, dependent on the cable loss. Their calculations were performed assuming cables with losses between 30 and 70dB/km at 850MHz. These low values can only be obtained using very expensive low loss cables with diameters > 1/2in...
متن کاملA Coaxial Cable Fabry-Perot Interferometer for Sensing Applications
This paper reports a novel coaxial cable Fabry-Perot interferometer for sensing applications. The sensor is fabricated by drilling two holes half-way into a coaxial cable. The device physics was described. The temperature and strain responses of the sensor were tested. The measurement error was calculated and analyzed.
