Reflection and Transmission Coefficients from Rectangular Notches in Pipes

open access: yesStrojniški vestnik – Journal of Mechanical Engineering, 2015
The use of a single, non-dispersive ultrasonic guided wave mode is one important approach to monitoring a structure’s health. It is advantageously non-destructive with the ability of propagating over tens of metres to detect a hidden defect. The dimensional assessment of a defect, on the other hand, requires reflection coefficients for two or more such

Experimental Study on Wave Transmission and Reflection at Impermeable Submerged Breakwaters

open access: yesInternational Journal of Coastal and Offshore Engineering, 2017
Submerged breakwaters are a special type of breakwater associated with low wave reflection. They can also save large quantities of engineering resources from the view of economics.

Asymptotic Formulas for the Reflection/Transmission of Long Water Waves Propagating in a Tapered and Slender Harbor

open access: yesJournal of Applied Mathematics, 2015
We obtain asymptotic formulas for the reflection/transmission coefficients of linear long water waves, propagating in a harbor composed of a tapered and slender region connected to uniform inlet and outlet regions.

Rigorous Bounds on Transmission, Reflection, and Bogoliubov Coefficients [PDF]

open access: yes, 2021
<p>This thesis describes the development of some basic mathematical tools of wide relevance to mathematical physics. Transmission and reflection coefficients are associated with quantum tunneling phenomena, while Bogoliubov coefficients are associated with the mathematically related problem of excitations of a parametric oscillator.

Propagation Characteristics of Oblique Incident Terahertz Wave in Nonuniform Dusty Plasma

open access: yesInternational Journal of Antennas and Propagation, 2016
Propagation characteristics of oblique incident terahertz wave from the nonuniform dusty plasma are studied using the propagation matrix method. Assuming that the electron density distribution of dusty plasma is parabolic model, variations of power ...
