We examine a numerical technique developed to simulate unsteady dispersion and diffusion in coated tubes of arbitrary but axially-constant cross-section. The method is validated against analytical asymptotic solutions produced for tubes of circular section, then applied to the study of dispersion in equivalent tubes of square section, coated on one, two, three or four walls, and in a family of ...

In high resolution methods applied to Uniform Linear Arrays (ULA), the pre-processing that consists in forcing the estimated Cross Spectral Matrix (CSM) to be Toeplitz by averaging its elements along its diagonals is known to increase drastically the resolving power: that is why it is always done in practise. However, this approach is limited to linear arrays because of the required Toeplitz st...

The main purpose of this work is to solve the problem electromagnetic scattering from a chiral cylinder arbitrary cross-section above an infinite perfect electric conducting (PEC) plane. Using image theory, reduced two cylinders in free-space. Surface equivalence principle used obtain three different equivalent problems for two-cylinder problem. Then, method moments these numerically. It known ...
