Mode shaping in multicore fibers

Optics Letters, 2007
We propose a novel multicore fiber design strategy for obtaining a flat in-phase supermode that optimizes utilization of the active medium inversion in the multiple cores. The spatially flat supermode is achieved by engineering the fiber so that the total mutual coupling between neighboring active cores is equal.

SENSITIVITY-BASED OPERATIONAL MODE SHAPE NORMALISATION

Mechanical Systems and Signal Processing, 2002
In the past few years, in-operation modal analysis has become a valid alternative for structures where classic forced vibration tests would be difficult, if not impossible, to conduct. A disadvantage of this method is that the excitation forces are unknown. Therefore, not all modal parameters can still be estimated.

Acoustic cavity modes in lens-shaped structures

The Journal of the Acoustical Society of America, 2003
A method for solving exactly the Helmholtz equation in parabolic rotational coordinates is presented using separability of the eigenfunctions and the Frobenius power series expansion technique. Two examples of interest in acoustics are considered and analyzed quasianalytically: The acoustic pressure in a cavity defined by two paraboloids (forming a ...

From operating deflection shapes towards mode shapes using transmissibility measurements

Mechanical Systems and Signal Processing, 2010
Abstract A transmissibility measurement is the traditional way of making a frequency response measurement when the excitation force cannot be measured. It is calculated in the same way as the admittance function, or transfer function. Whereas the admittance function is the ratio of response divided by force, transmissibility is the ratio of a ...
