Motivated by the forthcoming data from the E950 experiment at BNL for small angle polarized proton-carbon scattering we revisit the problem of Coulomb phase. The approximation usually used, with the momentum transfer squared (q 2) small compared to the inverse elastic slope, is not justified within the kinematics of the E950 experiment. We go beyond this approximation and derive a new rather si...

We propose a theoretical study on the electromagnetic wave scattering from layered structures with an arbitrary number of rough interfaces by using the small perturbation method and the small slope approximation. The interfaces are characterized by Gaussian height distributions with zero mean values and Gaussian correlation functions. They can be correlated or not. The electromagnetic field in ...

Bistatic radar cross sections are calculated using two modern scattering models: the small slope approximation (both firstand second-order) and the phase perturbation technique. The problem is limited to scalar-wave scattering from two-dimensional, randomly rough Diricblet surfaces with a Gaussian roughness spectrum. Numerical results for the cross sections are compared to those found using the...

This paper focuses on a hydraulic radius separation approach used to calculate the boundary shear stress in terms of bed and wall shear stress proposed in a trapezoidal channel. The average bed and sidewall shear stress in smooth trapezoidal open channels are derived after using Guo & Julien (2005) early equations taking a part of an investigation to cover both rectangular and trapezoidal chann...
