Reflection and transmission in regular dense arrays of dipole scatterers

IEEE Antennas and Propagation Society International Symposium. Transmitting Waves of Progress to the Next Millennium. 2000 Digest. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.00CH37118), 2002
A simple analytical boundary condition to model electromagnetic properties of planar regular dense array of dipole particles is developed for normal plane-wave incidence. The impedance condition connects the averaged tangential electric and magnetic fields on the array plane which leads to an equivalent transmission-line model.

Asymmetric Flux Pinning in a Regular Array of Magnetic Dipoles

Physical Review Letters, 1998
The effect of a regular array of magnetic dipoles embedded in a superconducting film was investigated. A large asymmetry in critical currents was found between when the magnetic dipoles are aligned and antialigned with respect to an externally applied magnetic field.

Application of tikhonov regularization to dipole glass relaxation function

Ferroelectrics, 1998
Abstract Relaxation distribution function g(τ) was derived from the experimental data of dielectric measurements by use of the Tikhonov regularization method of solving for the inverse solution of the integral transform defining the relaxation time distribution g(τ) in the dipole glass system undergoing the glass freezing. The distribution function g(τ)

Regularizing dipole polarizabilities in time-domain electromagnetic inversion

Journal of Applied Geophysics, 2012
Abstract Recent advances in time-domain electromagnetic (TEM) sensors have dramatically improved discrimination of buried unexploded ordnance (UXO). In contrast to commercial standard mono-static sensors, the multi-static, multi-component geometries of next generation TEM sensors provide diverse excitations of a detected target. Inversion of observed

Dipole-monopole criticality and chargeless half mode in an integrable gauge-coupled pseudoexciton-phonon system on a regular one-dimensional lattice

Physical Review E, 2023
A one-dimensional nonlinear dynamical system of gauge-coupled intrasite excitations and lattice vibrations on an infinite one-dimensional regular lattice is studied. The system as a whole is shown to be integrable in the Lax sense and it admits the exact four-component analytical solutions.

Regularities in calculated dipole moment derivatives of first row diatomic hydrides

The Journal of Chemical Physics, 1974
Calculated dipole moment derivatives from CNDO/2 wavefunctions for the first row diatomic hydride (XH) molecules are compared with the derivatives calculated by Cade and Huo from a near Hartree-Fock calculation. In making this comparison, a remarkably simple straight-line relationship is found to exist between these dipole moment derivatives and the ...

General regularities in the behavior of dipole moment functions of diatomic molecules at small internuclear separations

Atmospheric and Oceanic Optics, 2009
Based on the united atom model and the LS-coupling approximation, dipole moment functions were calculated for some diatomic molecules at small internuclear separations R. Families of molecules belonging to united atoms Li(2S), Na(2S), B(1P), Al(1P), and O(1D) were considered.

Regularities in the behavior of dipole moment functions of diatomic molecules at very small internuclear separations

Physical Review A, 2008
A theoretical approach to calculating the dipole moment function of a diatomic molecule at very small internuclear separations has been suggested. The approach is based on the united-atom model and the LS-coupling approximation. Regularities in the behavior of the dipole moments as functions of the internuclear separation, electronic state, and nuclear

An analytical model of the effective parameters of regular arrays of dipoles: from quasi-statics to PBG

IEEE Antennas and Propagation Society International Symposium. Transmitting Waves of Progress to the Next Millennium. 2000 Digest. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.00CH37118), 2002
This theory gives a model for the effective propagation constant in regular arrays of dipole particles which can be applied in a very wide frequency range from the quasi-static regime to the Bragg reflection (photonic band-gap) region.

Noise-induced enhancement of regular oscillations of a system of magnetic dipoles

Technical Physics, 2011
The dynamics of a system consisting of two bodies or a chain of bodies possessing dipole magnetic moments and moments of inertia is studied on the basis of numerical analysis. In constructing the parametric bifurcation diagram, the conditions for oscillatory modes with high noise sensitivity are determined. Features of this dynamics of coupled magnetic
