Coupled tension–torsion vibration of repetitive beam-like structures

Equivalent continuum stiffness properties, derived from the eigenanalysis of a single cell of a planar beam-like repetitive structure, have previously been employed within well-known dynamic theories, such as Euler–Bernoulli and Timoshenko for flexural vibration, suitably modified, to predict natural frequencies of vibration. Here the approach is applied to two structure types that exhibit tens...

Global plate vibration reduction using a periodic grid of vibration absorbers

This paper studies the potential of a periodic grid of vibration absorbers to achieve global plate vibration reduction. The global plate vibration reduction is pursued by applying the principles of resonance based stop bands. This principle is investigated both by infinite structure theory and by an example of a finite plate with a periodic grid of tuned resonators. Specific attention is paid t...

Finite-Difference Time-Domain Simulation of Light Propagation in 2D Periodic and Quasi-Periodic Photonic Structures

Ultra-short pulse is a promising technology for achieving ultra-high data rate transmission which is required to follow the increased demand of data transport over an optical communication system. Therefore, the propagation of such type of pulses and the effects that it may suffer during its transmission through an optical waveguide has received a great deal of attention in the recent years. We...
