Interaction of eigenmodes in a spherical dielectric resonator [PDF]
Радиофизика и электроника, 2019 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 ...

Eigenfrequencies and Vibration Modes of Carbon Nanotubes [PDF]
Civil-Comp Proceedings, 2014 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.

A Convenient Method to Obtain Stellar Eigenfrequencies [PDF]
International Astronomical Union Colloquium, 1983 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.

INTERACTION OF EIGENMODES IN A SPHERICAL PARTICLE WITH NEGATIVE VALUES OF ITS MATERIAL PARAMETERS
Radio Physics and Radio Astronomy, 2019 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.

Magnetic Perturbations to Stellar Oscillation Eigenfrequencies [PDF]
Symposium - International Astronomical Union, 1988 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.
