INTERACTION OF PLANE WAVES WITH VERTICAL CYLINDERS

Nonlinear front evolution of hydrodynamic chemical waves in vertical cylinders

Interaction of hydro-elastic waves with a vertical wall

This study aims to gain knowledge on how hydroelastic waves interact with off-shore structures, for example off-shore wind turbines or oil rigs. The linear two-dimensional problem of hydroelastic waves reflected by a vertical wall is analysed. Water is of finite depth and is covered by ice. The fluid is assumed incompressible and inviscid. The ice sheet is assumed thin compared with both the wa...

Scattering of Plane Waves on Finite Cylinders with Non-circular Cross-sections

Numerical prediction of guided waves interaction with non-axisymmetric cracks in elastic cylinders

The interaction of guided waves with non-axisymmetric damages in cylinders is studied. A three dimensional hybrid method involving the classical Finite Element Method (FEM) and the Semi-Analytical Finite Element (SAFE) technique is developed. The damage and its near field are analysed with the standard FEM. Then, eigenmode expansions of the solutions at both inlet and outlet cross-sections of t...

Surface polaritons of small coated cylinders illuminated by normal incident TM and TE plane waves.

The surface polariton properties of TM or TE plane wave scattered by a coated cylinder are investigated in this paper. The coated cylinder (whose outer radius is much smaller than the wavelength) is assumed to be electrically small and low dissipative. Analytical formulas of the plasmonic resonances are derived and found to agree well with those obtained from exact expressions in the classical ...
