this paper presents an investigation on the effect of temperature and raw material on microstructure of fine cellular foam used as the insulation of coaxial cables. a set up was prepared and used to produce fine cellular foamed insulation. as the physical  blowing agent, butane was used. the effect of temperature on the microstructure of polyethylene (pe) was worth to note. at high temperature,...

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...

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...

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.

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.

Usingjnmdtfiiax cable (coaxial cable with additional coaxial shields, ihssil~t@cd from each other), techniques are discussed which allmwa@muthaY distribution of the signal input positions around a Ensppst.rructure. Also discussed are uses of this kind of multiax cab3e:’:structure for multi-turn loops. In some cases there are Wppcmvements in ttie performance of loops (for measurinq the mazgwtt~c...

This paper reports the experimental demonstration of a coiled coaxial cable resonator capable of meeting the critical coupling condition using a reduced number of coils relative to previously reported coiled resonators. By introducing a second slot along the length of the device, a two-slot coiled coaxial cable resonator was fabricated and critical coupling observed at 22 turns. An additional d...

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...
