Neurocomputed model of open-circuited coaxial probes
IEEE Microwave and Guided Wave Letters, 1995An artificial multi-layered feedforward neural network has been developed which transforms reflection coefficient data measured using a coaxial probe and network analyser, into the permittivity values of the fluid the probe touches. This eliminates the need for de-embedding of data from the measurement plane via empirical models of the physical cable ...

Coaxial helium leak detection probe
Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 1987A coaxial device has been developed which makes it possible to pinpoint a leak in a piece of vacuum hardware or tubing within a space of one-sixteenth of an inch. The device consists of a delivery tube which directs the helium to a precise spot and a coaxial outer tube which pumps away the excess helium.

Coaxial pulse voltage probe with adjustable sensitivity
High Power Laser and Particle Beams, 2014A coaxial pulse voltage probe is designed to measure the signal through the input of TEM cell or GTEM cell in calibrating electromagnetic pulse(EMP) sensors. The output differential signal of the probe can be converted by numerical integration to obtain the measured EMP field, and the measurement sensitivity can be adjusted.

A Novel Coaxial Probe Waveguide to Microstrip Transition
2005 Asia-Pacific Microwave Conference Proceedings, 2006In this paper, a modified coaxial probe waveguide-to-microstrip transition structure at K-band is proposed. The transition uses two kinds of coaxial probes and has hermetic characteristics. It can also be used in other band, such as Ka-band. The structure is demonstrated for designing the transition.

Novel Coupling Structure for the Resonant Coaxial Probe
IEEE Transactions on Microwave Theory and Techniques, 2012Herein we present a technique for performing complex permittivity measurements with an overmoded, evanescently perturbed coaxial resonator at microwave frequencies. The design of a noninvasive electromagnetic coupling structure, which allows transmission measurements to be taken from one end of a resonant section of coaxial cable, is discussed in ...

Analytical Modeling of a Coaxial Probe in a Waveguide Device
2018 International Conference on Electromagnetics in Advanced Applications (ICEAA), 2018This work presents a study about a analytical technique used to model the wave coupling from a coaxial line fed probe to a waveguide device with promising applications in the Additive Manufacturing (AM). The analytical technique estimates the input impedance of the probe based in dyadic Greens functions.

Coaxial probe dielectric measurements in the presence of airgaps
Proceedings of 6th Electronics Packaging Technology Conference (EPTC 2004) (IEEE Cat. No.04EX971), 2005Interpolation formulas for retrieval of the dielectric constant of the substrate from the measured probe impedance within a specified frequency range are introduced. The proposed formulas were tested for retrieval of dielectric constant from impedance measurements for the substrates with known properties.

Coaxial D-dot probe: design and testing
Proceedings of 1995 Conference on Electrical Insulation and Dielectric Phenomena, 2002A new coaxial D-dot probe is designed and calibrated. A charge simulation programme is used to get the best configuration and arrangement of the probe design. The calibration is made against a conventional capacitive divider. The designed probe shows faster response and eliminates inductive overshoot to some extent.
