Traveling Waves and Power Waves
M icrowave equivalent-circuit theory is like a grand old building: elegant, carefully crafted, passed from generation to generation, and rooted in history. Traveling waves, the measureable electromagnetic field solutions of Maxwell’s equations in a transmission line, form the foundation of the theory. You must descend into the basement to see them; not many people do so. It is in this “basement...
متن کاملTraveling Waves for the Whitham Equation
The existence of traveling waves for the original Whitham equation is investigated. This equation combines a generic nonlinear quadratic term with the exact linear dispersion relation of surface water waves of finite depth. It is found that there exist small-amplitude periodic traveling waves with sub-critical speeds. As the period of these traveling waves tends to infinity, their velocities ap...
متن کاملTraveling Waves in
For a class of 1-dimensional lattice dynamical systems we prove the existence of periodic traveling waves with prescribed speed and arbitrary period. Then we study asymptotic behaviour of such waves for big values of period and show that they converge, in an appropriate topology, to a solitary traveling wave.
متن کاملDirection-reversing traveling waves
The symmetries of a physical system provide a key to much of its dynamical behavior. As a consequence equivariant bifurcation theory has met with remarkable success in a wide range of physical applications, including fluid dynamics, laser physics, and chemical oscillations. (See, for example, refs. [1,2].) In this note we consider physical systems depending on a parameter/~ that are translation...
متن کاملTraveling waves for anomalous diffusion in polymers
case II diffusion of a penetrant through a polymer matrix is characterized by constant front speed. Hence, a traveling-wave analysis is appropriate for the model equations. For the previously validated model analyzed here, conditions on the molecular and stress diffusion coefficients are obtained which guarantee the existence of a traveling wave. Conditions are derived under which an interior m...
