Efficient Statistical Extraction of the Per-Unit-Length Capacitance and Inductance Matrices of Cables with Random Parameters

open access: yesAdvanced Electromagnetics, 2015
Cable bundles often exhibit random parameter variations due to uncertain or uncontrollable physical properties and wire positioning. Efficient tools, based on the so-called polynomial chaos, exist to rapidly assess the impact of such variations on the ...

Insulated Wire Fed Floating Monopole Antenna for Coastal Monitoring [PDF]

open access: yesRadioengineering, 2018
A thin, flexible, insulated wire submerged in seawater forms a coaxial cable which has attenuation at ultra-high frequency (UHF) dependent on the operating frequency, the diameter of the insulating material and the diameter of the inner conductor.

Modeling dispersion of partial discharges due to propagation velocity variation in power cables [PDF]

open access: yes, 2016
Existing models for partial discharge (PD) propagation based on a single attenuation constant are unable to explain how each frequency component travels with a different propagation velocity. This paper proposes a new model based on a complex propagation
