Dispersion Evaluation In Optical Wave Guides
One of the factors which limits the transmission capacity of the fiber optics communication channel is the material dispersion. Exact analytical study of the material dispersion is often complex and involves calculating the derivatives of the refractive index of the core. These calculations are too cumbersome to do, especially for high-order derivatives. So material dispersion has only been stu...

متن کاملNumerical computation of wave breaking times
The time of nonlinear wave collapse is computed numerically for the Hopf equation. Previous numerical criteria for locating the time of wave collapse are either computationally prohibitive to implement or give erroneous results. A new criterion for this purpose is developed analytically using asymptotic analysis of the wave shock development shortly after breaking. The criterion defines the wav...
متن کاملCharacterization of thin films using generalized lamb wave dispersion relations
We used the Continuous Wave Scanning Acoustic Microscope to characterize thin film materials. The measurement of the dispersion curve of surface waves and the inversion of this dispersion equation relation, allow to determine the elastic constants, the density or the thickness of a thin layer on a substrate. Besides, it is possible to have qualitative information on the adhesion properties of t...
