Binary wave in a helical fiber
نویسنده
چکیده
Axial dynamic tension of a flexible helical fiber is found to lead to a specific, extraordinary nonlinear wave consisting of two different portions. The leading portion is a quasiperiodical propagating wave with rotation opposite to the initial twist of the helix, while the rear portion is a sequence of standing waves rotating in the reverse direction. The interface is the origin of two angular-momentum fluxes which, being different in sign, fill up angular momenta of the leading and rear waves. The phenomenon described presents an interesting example of a zero-total-angular-momentum wave propagating in a twisted waveguide. @S0163-1829~97!08021-1#

Wave Motion and Stop-Bands in Pipes with Helical Characteristics Using Wave Finite Element Analysis
Pipes are widely used in many industrial and mechanical applications and devices. Although there are many different constructions according to the specific application and device, these can show helical pattern, such as spiral pipes, wire-reinforced pipes/shells, spring-suspension, and so on. Theoretical modelling of wave propagation provides a prediction about the dynamic behavior, and it is f...
متن کاملTowards the Dispersion Relations for Dielectric Optical Fibers with Helical Windings under Slow- and Fast-wave Considerations — a Comparative Analysis
The paper presents the electromagnetic (EM) wave propagation in cylindrical optical fibers with helical windings under slowand fast-wave considerations. Field components are deduced for both the cases, and also, the dispersion relations are obtained by applying the boundary conditions, as modified by the presence of conducting helical windings. Two special cases are considered corresponding to ...
متن کاملDispersion of Love Wave in a Fiber-Reinforced Medium Lying Over a Heterogeneous Half-Space with Rectangular Irregularity
This paper concerned with the dispersion of Love wave in a fiber-reinforced medium lying over a heterogeneous half-space. The heterogeneity is caused by the consideration of quadratic variation in density and directional rigidity of lower half-space. The irregularity has been considered in the form of rectangle at the interface of the fiber-reinforced layer and heterogeneous half-space. The dis...
متن کاملLove Wave Propagation in a Fiber-reinforced Layer with Corrugated Boundaries Overlying Heterogeneous Half-space
Love-type wave generation in a fiber-reinforced medium placed over an inhomogeneous orthotropic half-space is analysed. The upper and lower boundary surfaces of the fiber reinforced medium are periodically corrugated. Inhomogeneity of half-space is caused by variable density and variable shear modules. Displacement components for layer and half-space are derived by applying separable variable t...
متن کاملWave Propagation in a Layer of Binary Mixture of Elastic Solids
This paper concentrates on the propagation of waves in a layer of binary mixture of elastic solids subjected to stress free boundaries. Secular equations for the layer corresponding to symmetric and antisymmetric wave modes are derived in completely separate terms. The amplitudes of displacement components and specific loss for both symmetric and antisymmetric modes are obtained. The effect of ...
