摘要:
AbstractThe asymptotic form, for high frequencies, of the equations of propagation on a nonuniformN‐conductor transmission line is considered. Under the assumption of perfect conditions in uniform, isotropic media, allNpropagation velocities are the same, but the characteristic impedance matrix is allowed to vary with position along the line. Closed‐form solutions are obtained for some cases of inter

摘要:
AbstractA numerical method using impulse analysis of a transmission‐line matrix is used to model the scattering of underwater acoustic waves. The method is demonstrated by observation of plane and curved wavefronts travelling through the medium, and by plane wavefronts being scattered by a reflecting boundar

摘要:
AbstractShooting and bouncing rays (SBR) is a numerical method based on geometric optics developed to compute the electromagnetic scattering from jet inlets and partially open cavity structures. This method is used to study the effects of shaping on the radar cross‐section (RCS) of cavities. Two cylindrical cavity structures are analysed: one with a uniform circular cross‐section, and the other with a non‐uniform cross‐section varying from a triangular shape to a circular shape. By bending the longitudinal axis of a cylindrical cavity, a significant reduction in RCS at near axial incidence can be a

摘要:
AbstractThe development of numerical models to describe physical problems with irregular boundaries frequently involves the use of very fine or variable Cartesian meshes when a more descriptive mesh might be appropriate. This paper describes the application of the transmission line matrix (TLM) technique to the analysis of orthogonal curvilinear mesh problems. Although very high levels of accuracy are possible, the computational efficiency may be reduced owing to the stub admittance factor,S, and the need for an accurate evaluation of the transmission line parameters.
