The proposed theorem in this paper is indicative of a kind of duality in the propagation of waves in the dual media of and in the spherical structures. Independent of wave frequency, the number of layers, their thickness, and the type of polarization, this theorem holds true in case of any change in any of these conditions. Theorem: Consider a plane wave incident on a multilayered spheric...

Bayguinov O, Ward SM, Kenyon JL, Sanders KM. Voltage-gated Ca currents are necessary for slow-wave propagation in the canine gastric antrum. Am J Physiol Heart Circ Physiol 293: C1645–C1659, 2007. First published September 13, 2007; doi:10.1152/ajpcell.00165.2007.— Electrical slow waves determine the timing and force of peristaltic contractions in the stomach. Slow waves originate from a domina...

This paper deals with the development of a computer model for flood routing in narrow rivers. Equations describing the propagation of a flood wave in a channel-flood plain system are presented and solved using an implicit finite difference scheme. Particular emphasis has been given to the treatment of the friction term in the governing equation of motion.

A validation study of the distinct lattice spring model (DLSM) for wave propagation problems is performed. DLSM is a microstructure-based numerical model, which is meshless and has advantages in modelling dynamic problems where stress wave propagation is important. To verify the applicability of DLSM to modelling wave propagation through a discontinuous medium, the virtual wave source (VWS) met...

The fundamental solution of the system of differential equations in bio-thermoelasticity with dual phase lag (DPL) in case of steady oscillations in terms of elementary function is constructed and basic property is established. The tissue is considered as an isotropic medium and the propagation of plane harmonic waves is studied. The Christoffel equations are obtained and modified with the ther...

In order to guarantee the service quality and reliability for mobile satellite communication systems, we have to take into account outages due to obstruction of the line-of-sight path between a satellite and a mobile terminal as well as the signal fluctuation caused by interference from multipath radio waves. Thus, we need a good characterization for the satellite propagation channel. In this p...

High frequency / short pulse wave propagation modeling and simulation strategies will be reviewed in this presentation invited for the special session honoring Prof. Leopold B. Felsen on his 80 birthday. INTRODUCTION Narrow and broad band wave propagation either natural or man-made environments are of interest for many decades, since the success and quality of any communication depends directly...

It is well known that the wave propagation depends mainly on its velocity and frequency in one direction for a single wave[1-3]. There are many literatures devoted researches of single wave propagation such as solitary wave, periodic wave, chirped wave, rational wave etc [4-6]. However, what can be happen when two and even more waves with different features propagate together along different di...

This paper describes an investigation of the source geospatial error in digital surface models (DSMs) constructed from multiple satellite images. In this study uncertainty geometry is separated into two spatial components; global that affects absolute position surface, and local varies point to point. The component caused by inaccuracy imaging process, mainly due orientation (pose) during image...
