Environmental Design of Low Crested Coastal Defence Structures

Reflection and Transmission of Longitudinal Wave at Micropolar Viscoelastic Solid/Fluid Saturated Incompressible Porous Solid Interface

In this paper, the reflection and refraction of longitudinal wave from a plane surface separating a micropolar viscoelastic solid half space and a fluid saturated incompressible half space is studied. A longitudinal wave (P-wave) impinges obliquely at the interface. Amplitude ratios for various reflected and transmitted waves have been obtained. Then these amplitude ratios have been computed nu...

Physical and Numerical Modeling of Beach Response to Permeable Low-Crested Coastal Structures

Detached breakwaters are often employed to protect beaches against erosion. When these structures are frequently overtopped, they are named Low-Crested Structures (LCS). These LCS’s offer a number of potential advantages over conventional structures, but their functional design is extremely difficult due to the large number of different processes contributing to the resulting water/sediment flu...

Transmission properties of one dimensional fractal structures

In this paper, the optical properties of one dimensional fractal structures are investigated. We consider six typical fractal photonic structures: the symmetric dual cantor-like fractal structure, the asymmetric dual cantor-like fractal structure, the single cantor-like fractal structure, the symmetric dual golden-section fractal structure, the asymmetric dual golden-section fractal structure a...
