PA-DETR: End-to-End Visually Indistinguishable Bolt Defects Detection Method Based on Transmission Line Knowledge Reasoning

IEEE Transactions on Instrumentation and Measurement, 2023
A transmission line is the lifeline of a power system, while bolts play the role of connecting fittings and tightening conductors. However, bolts at different positions have different definitions of defects, which belongs to the problem of visually ...

Transmission Line Model for Simulation of Guided-Wave Defect Signals in Piping

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2004
A simple transmission line model for analytically simulating the guided-wave signal reflected from a volumetric defect of arbitrary shape in piping is described. In the model, the guided-wave interaction with a defect is treated as the one-dimensional problem of plane wave reflection from a boundary of multilayered media of different acoustic ...

Balance dipole antenna with defect differential transmission line

2016 Progress in Electromagnetic Research Symposium (PIERS), 2016
The radiation pattern of a balance dipole antenna feeds with odd mode (or differential mode) transmission line is symmetry for H-plane pattern. Unfortunately, if the transmission line is a single ended or defect odd mode the radiation pattern will be vector summation of antenna itself and the unbalance transmission.
