Perfectly Matched Layer (PML) for Transient Wave Propagation in a Moving Frame of Reference

, 2013
In relation to the development of a Rolling Wheel Deflectometer (RWD), which is a non-destructive testing device for measuring pavement deflections, a finite element model for obtaining the soil/pavement response is developed. Absorbing boundary conditions are necessary in order to prevent reflections of the waves propagating through the soil due to ...

Frequency-Domain Finite Element Modeling of Seismic Wave Propagation Under Different Boundary Conditions

Mathematics
Seismic wave propagation in complex terrains, especially in the presence of air layers, plays a crucial role in accurate subsurface imaging. However, the influence of different boundary conditions on seismic wave propagation characteristics has not been ...

Transverse Wave Propagation in Functionally Graded Structures Using Finite Elements with Perfectly Matched Layers and Infinite Element Coupling

Mathematics
This study investigates the propagation of shear horizontal transverse waves in a functionally graded piezoelectric half-space (FGPHS), where the material properties vary linearly and quadratically.

Ultrahigh effective mode area photonic crystal fibers with extremely low bending loss for long distance transmission application

Sensing and Bio-Sensing Research
In this work, an extremely large mode area (LMA) photonic crystal fiber (PCF) design has been proposed having single mode operation. A full-vectorial finite element method (FEM) approach is considered with perfectly matched layer (PML) boundary for ...
