A New Approach to the Study of Transverse Vibrations of a Rectangular Plate Having a Circular Central Hole
In this study, the analysis of transverse vibrations of rectangular plate with circular central hole with different boundary conditions is studied and the natural frequencies and natural modes of a rectangular plate with circular hole have been obtained. To solve the problem, it is necessary to use both Cartesian and polar coordinate system. The complexity of the method is to apply an appropria...
متن کاملExact solution of resonant modes in a rectangular resonator.
The resonant modes of rectangular two-dimensional optical resonators were analyzed exactly. Based on the characteristics of the Bessel function, the resonant frequencies of the rectangular microcavities are expressed in a simple way. In addition, a simple rule to judge when the finite length of a rectangular resonator can be considered infinite is given in realistic applications. The solution t...
متن کاملAttenuation Constants of Radio Waves in Lossy-walled Rectangular Waveguides
At the ultra-high frequencies (UHF) common to portable radios, the mine tunnel acts as a dielectric waveguide, directing and absorbing energy as a radio signal propagates. Understanding radio propagation behavior in a dielectric waveguide is critical for designing reliable, optimized communication systems in an underground mine. One of the major parameters used to predict the power attenuation ...
متن کاملNonlinear interaction of transverse modes in a CO2 laser.
We show the possibility of achieving experimentally a Takens-Bogdanov bifurcation for the nonlinear interaction of two transverse modes (l = ±1) in a CO2 laser. The system has a basic O(2) symmetry which is perturbed by some symmetrybreaking effects that still preserve the Z2 symmetry. The pattern dynamics near this codimension two bifurcation under such symmetries is described. This dynamics c...
متن کاملTransverse Modes in Large-Mode-Area Fibers
This thesis is devoted to the study of transverse modes in large-mode-area (LMA) fibers. It highlights the importance of transverse spatial-hole burning (TSHB) effect in LMA multimode fibers through experiments and simulations. The measured beam-quality factor decreases until the gain becomes saturated in an amplified spontaneous emission (ASE) source based on an Yb-doped LMA multimode fiber. A...
