We report the first observation of discrete Talbot revivals in one-dimensional waveguide arrays. Unlike continuous systems where the Talbot self-imaging effect always occurs irrespective of the pattern period, in discrete configurations this process is only possible for a specific set of periodicities. Recurrence of different input periodic patterns is observed in good agreement with theory.

The slotted waveguide slow-wave stochastic cooling arrays are an integral part of the 4-8 GHz Debuncher Upgrade at FNAL. Unlike the standard array of stripline electrodes, these structures are designed to work when the beam pipe can support many microwave modes. The design theory and beam measurement results of this new type of pickup structure will be presented in this paper.

Electromagnetic bandgap structures formed by circular posts of magnetized ferrite stacked in a rectangular waveguide is analyzed using the image theory, the lattice sums technique, and the generalized reflection and transmission matrices. The frequency response controllable by the applied magnetic field are discussed for the incidence of the fundamental 10 TE mode.

This diploma thesis deals with physical effects in the light output of a vertical cavity surface emitting laser (VCSEL) diode caused by external optical feedback. Such feedback might be induced by reflections from the beginning of a optical waveguide due to a connected refractive index step. The thesis also investigates the influence on waveguide coupled power on opto-electronic waveguide board...

Optical waveguide theory is essential to the development of various optical devices. Although there are reports on waveguides with magneto-optical (MO) and magnetoelectric (ME) effects, a comprehensive theoretical analysis considering these two effects has not yet been published. In this study, conventional extended by constitutive relations that account for both MO ME effects. Using theory, pr...

in this article, the effect of cells' radius on the behavior of wavelength switching optical filter andthe effect of the radius of the optical filters' key characteristics such as wavelength resonance onan optical filter based on photonic crystals, have been investigated. currently, the most commonapplied mechanism for designing optical filter based on photonic crystals is using twome...

One of the most successful theories to date to explain why observed planetary waves propagate westwards faster than linear flat-bottom theory predicts has been to include the effect of background baroclinic mean flow, which modifies the potential vorticity waveguide in which the waves propagate. (Barotropic flows are almost everywhere too small to explain the observed differences.) That theory ...

This work presents a design technique to implement miniaturized cross-coupled bandpass filters in inline physical configurations based on triple-mode resonators. Triple-mode resonances are obtained by using integrated coaxial-waveguide cavity They consist of two coaxial conducting posts placed the sidewalls rectangular waveguide cavity. In proposed triplet, transmission zero (TZ) can be positio...

The formalism of coupled-mode theory is adopted for describing nonlinear pulse propagation in optical fibers, the coupling being induced by the nonlinear part of the refractive index. This approach describes in a natural way the influence of the waveguide, and in principle allows of the possibility of investigating soliton propagation when more than one mode is excited.
