A combination of asymptotic approach and computational modeling is used for solution of problem to investigate the backscattering of several small particles embedded in fluid medium. The initial diffraction problem of wave scattering by many small particles is developed under the assumption ka ≪1, d ≫ a, where a is the size of the particles and d is the distance between the neighboring particles....
In the following paper we present a complete analytical model that predicts the band-gap (Eg) of single-walled carbon nanotubes (SWCNTs) directly from their diameter (d) and chiral angle (thetas). The proposed analytical model is based on two mathematical expressions that have been derived by curve-fitting the outcome generated from the third-nearest-neighbor tight-binding (TB) method in conjunction...
We report on the design and experimental validation of a distributed Brillouin-based optical fiber sensor embedded into concrete structures for temperature and strain measurement. A composite-made wave-like coating designed by finite-element analysis ensures the sensor is transferring optimally temperature and strain fields from the concrete to the optical fiber, where Brillouin scattering takes place...
