This paper presents a three dimensional application of direct Boundary-Element Method (BEM) for computing interaction of sinusoidal waves with a large submerged open bottom structure near the floor with finite depth. The wave diffraction problem is formulated within the framework of linearized potential theory and solved numerically with direct BEM. A computer program based on BEM is developed ...

An unexplained acceleration on the order of 10–8 cm s–2, which is close to cH, where c speed light and H Hubble constant, detected in gravitationally bound systems different scales, from solar system clusters galaxies. We found that any test body located inside a fractal structure with dimension D = 2 experiences same confirmed previous work photons propagating through this decrease frequency o...

We design, optimize, fabricate, and characterize highly reflective quasi-omnidirectional multilayered structures with a wide angular spectral range. consider chirped layers of gradually varying thicknesses made by stacking Bragg-type sub-structures, we maximized their numerically calculated reflectance averaged over different ranges keeping minimum thickness for given pairs refractive indices. ...
