Wave scattering in one dimension with absorption
Wave scattering is analyzed in a one-dimensional nonconservative medium governed by the generalized Schrödinger equation dc/dx1kc5@ ikP(x) 1Q(x)#c , where P(x) and Q(x) are real, integrable potentials with finite first moments. Various properties of the scattering solutions are obtained. The corresponding scattering matrix is analyzed, and its small-k and large-k asymptotics are established. Th...
متن کاملBounds on Scattering Poles in One Dimension
For the class of super-exponentially decaying potentials on the real line sharp upper bounds on the counting function of the poles in discs are derived and the density of the poles in strips is estimated. In the case of nonnegative potentials, explicit estimates for the width of a pole-free strip are obtained.
متن کاملMethods in wave propagation and scattering
Aspects of wave propagation and scattering with an emphasis on specific applications in engineering and physics are examined. Frequency-domain methods prevail. Both forward and inverse problems are considered. Typical applications of the method of moments to rough surface three-dimensional (3-D) electromagnetic scattering require a truncation of the surface considered and call for a tapered inc...

Of course, reading will greatly develop your experiences about everything. Reading wave propagation and scattering in random media is also a way as one of the collective books that gives many advantages. The adv...
متن کاملDispersive wave turbulence in one dimension
In this article, we study numerically a one-dimensional model of dispersive wave turbulence. The article begins with a description of the model which we introduced earlier, followed by a concise summary of our previous results about it. In those previous studies, in addition to the spectra of weak turbulence (WT) theory, we also observed another distinct spectrum (the “MMT spectrum”). Our new r...
