Propagation of Waves in Helical Wave Guides [PDF]
Journal of Applied Physics, 1958 The field configuration near the conductors of a helical wave guide is obtained from the solution of the spatial-wave equation for a developed helix. This solution is first obtained for the case of tape conductors and then adapted to elliptical (including circular) conductors by conformal transformation.

Managing Complexity, Uncertainty, and Variability in Guided Wave Structural Health Monitoring
SICE Journal of Control, Measurement, and System Integration, 2017 Guided waves are an attractive tool for monitoring large structures. They are able to interrogate sizable areas at once, are sensitive to structural damage, and carry information about the damage location.

The Hitchhiker’s Guide to the Wave Function
The Journal of Physical Chemistry A, 2022 The electronic wave function of molecules is 3N-dimensional and inseparable in the coordinates of the N electrons. Whereas molecular orbitals are often invoked to visualize the electronic structure, they are nonunique, with the same 3N-dimensional wave function being represented by an infinite number of 3-D, one-electron functions (orbitals ...

Shear-horizontal guided wave tomography [PDF]
, 2022 The petrochemical industry’s pipe-network is increasingly suffering from corrosion-induced shutdowns and thus a quantitative measurement approach is vital for making adequate service-life predictions and to guarantee safety. At pipe-supports, access is

Open Guided Waves: online platform for ultrasonic guided wave measurements [PDF]
Structural Health Monitoring, 2018 Ultrasonic guided waves have been used successfully in structural health monitoring systems to detect damage in isotropic and composite materials with simple and complex geometry. A limitation of current research is given by a lack of freely available benchmark measurements to comparatively evaluate existing methods.
