The state vector in the physical domain is transformed to the wave domain using displacement and internal force matrices. The wave amplitudes at one point are then related to those at another point by a propagation matrix, which is diagonal for the cases considered. By normalising the elements ...

The wave propagation in a simply supported travelling beam, studied in Part I of this paper, has been used to derive the forced responses. Based upon the wave-propagation principles, a simple method for constructing the closed-form transfer function of such a beam has been presented. The use...
A numerical study of wave propagation through gases with non-uniform temperature distributions will be presented. The aim of this study is to determine the impact of temperature gradients on high-intensity pressure waves of various initial wave forms. Emphasis is paid to wave reflection and transmiss...
The aim of the investigation is to simulate the interaction of an ion Bernstein wave (IBW) with a collisionless plasma. The problem is dealt with in the frame of a one‐dimensional slab model, where all physical quantities vary in the direction of wave propagation. Electrons constitute a ...
Therefore, the existence of the asymmetric modes at all frequencies leads to an extremely large level of nonreciprocal transmission over a very large range of frequencies, a performance that is unprecedented among wave-based physical systems. Since the nonreciprocal transmission is broadband, our ...
The method of multiple scales is used to analyze three non-linear physical systems which support dispersive waves. These systems are (i) waves on the interface between a liquid layer and a subsonic gas flowing parallel to the undisturbed... AH Nayfeh,SD Hassan - 《Journal of Fluid Mechanics》...
