The Distribution of Eigenfrequencies of Anisotropic Fractal Drums [PDF]
Let \(\Gamma\) be an anisotropic fractal as it was defined by \textit{H. Triebel} in the book ``Fractals and spectra related to Fourier analysis and function spaces.'' (Birkhäuser, Basel, 1997), see Definition 5.2. The aim of the paper is to investigate the distribution of the eigenvalues of the fractal differential operator \((-\Delta)^{-1}\circ \text{

Interaction of eigenmodes in a spherical dielectric resonator [PDF]
Subject and purpose. It is known that with a change in the relative dielectric constant of a ball, for some of its eigenfrequencies and the corresponding eigenoscillations, anomalous behavior is characteristic (deviation from the norm in the behavior of ...

Tailored Microcantilever Optimization for Multifrequency Force Microscopy
Microcantilevers are at the heart of atomic force microscopy (AFM) and play a significant role in AFM‐based techniques. Recent advancements in multifrequency AFM require the simultaneous excitation and detection of multiple eigenfrequencies of ...

On the Eigenfrequencies of an Ordered System of Nanoobjects [PDF]
A method is discussed to determine the eigenfrequencies of nanostructures (nanotubes, nanospheres, and nanocrystals) by measuring the eigenfrequencies of a ‘large system’ that consists of an array of vertically oriented similar nanotubes or nanocrystals equidistantly grown on a substrate.

Eigenfrequencies and Vibration Modes of Carbon Nanotubes [PDF]
In 1991 Iijima discovered Carbon Nanotubes, he synthesised molecular carbon structures in the form of fullerenes and then reported the preparation of a new type of finite carbon structure consisting of needle-like tubes, the carbon nanotubes, described as helical microtubules of graphitic carbon.

INTERACTION OF EIGENMODES IN A SPHERICAL PARTICLE WITH NEGATIVE VALUES OF ITS MATERIAL PARAMETERS
Purpose: The behavior of spectral characteristics (eigenfrequencies, natural oscillations, Q-factors) of a spherical particle whose permittivity and permeability simultaneously take on negative values (a “left-handed” sphere) is considered.

A Convenient Method to Obtain Stellar Eigenfrequencies [PDF]
AbstractThe differential equations describing stellar oscillations are transformed into an algebraic eigenvalue problem. Frequencies of adiabatic oscillations are obtained as the eigenvalues of a banded real symmetric matrix. We employ the Cowling-approximation, i.e.

Spatial natural vibrations of viscoelastic axisymmetric structures [PDF]
A mathematical model, methods and algorithm to assess the spatial natural vibrations of axisymmetric structures are given in the paper taking into account the variability of the slope and structure thickness in the framework of the viscoelastic theory of

Magnetic Perturbations to Stellar Oscillation Eigenfrequencies [PDF]
Magnetic fields contribute to the splitting of the degeneracy of modes of like order and degree. The splitting is estimated for some simple hypothetical toroidal magnetic field configurations in the sun, and the results are compared with previous asymptotic estimates.
