Analysis of the Influence of Silicone Rubber Aging on the Transmission Parameters of Terahertz Waves
Energies, 2021 In this study, a method for testing the aging of silicone rubber insulators using terahertz waves in the 0.17–0.22 THz frequency band is proposed, aiming at the problem of online non-destructive testing of the aging degree of composite insulators.

Time dilation of a bound half-fluxon pair in a long Josephson junction with a ferromagnetic insulator [PDF]
, 2007 The fluxon dynamics in a long Josephson junction with a ferromagnetic insulating layer is investigated. It is found that the Josephson phase obeys a double sine-Gordon equation involving a bound pi fluxon solution, and the internal oscillations of the ...

Influencing factors in insulation model testing
Journal of Energy - Energija, 2022 The aim of this paper is to examine different factors that influence the quality of insulation models high voltage testing results. These factors are related to model geometry and model testing procedures. Model geometry is visually checked, several influencing factors are detected and their influence on el. field calculation results is evaluated using

$Sr Cu_2 (BO_3)_2$: A Unique Mott Hubbard Insulator
, 2002 We discuss the recently discovered system $Sr Cu_2 (BO_3)_2$, a realization of an exactly solvable model proposed two decades earlier. We propose its interpretation as a Mott Hubbard insulator.
