Switchable high-Q electromagnetically induced transparency based on the Ge2Sb2Te5 nanodisk dimers
Results in Physics, 2023 Bound states in the continuum (BICs) based on metasurfaces have gained significant attention recently to enhance the strength of light-matter interaction. However, most BIC metasurfaces possess fixed optical properties once they have been fabricated.

On the Particle Motion in Paleo‐Magnetosphere During the Geomagnetic Polarity Reversal
Geophysical Research Letters, 2023 During the Earth's magnetic reversal, the dipole component of the magnetic field weakens, and the non‐dipole component becomes dominant, resulting in a far more complex magnetospheric topology than that of a dipole.

qPlus magnetic force microscopy in frequency-modulation mode with millihertz resolution
Beilstein Journal of Nanotechnology, 2012 Magnetic force microscopy (MFM) allows one to image the domain structure of ferromagnetic samples by probing the dipole forces between a magnetic probe tip and a magnetic sample. The magnetic domain structure of the sample depends on the alignment of the

The field-induced interaction between non-resonant magnetic dipoles [PDF]
J. Phys. B, 53, 065003 (2020), 2019 We make a general derivation for the magnetic dipole-dipole interaction based on the mediation of the quantized electro-magnetic field. Due to the interaction with the dipoles, the dynamics of the field is added by a dipole field, which finally gives rise to the dipole-dipole interaction. Different from previous studies, the rotating-wave-approximation

Nanoscale Research Letters, 2018 We investigate the modification of the magnetic dipole resonance of a silicon nanosphere, which is illuminated by a focused azimuthally polarized beam, induced by a metal substrate.

Ultraviolet light scattering by a silicon Bethe hole
Nanophotonics, 2023 Bethe’s theory predicts that scattering by a small hole on a thin perfect electric conductor (PEC) is presented as radiation by an in-plane magnetic dipole of the incident magnetic field direction. Even in the near-infrared range where metals are no more

Electric dipole in a magnetic field: some aspects of the problem [PDF]
arXiv, 2021 In the paper some regimes of motion of an electric dipole placed in a uniform magnetic field are considered. The motion of both three-dimensional and two-dimensional dipole in the plane perpendicular to the magnetic field is studied. In the case of a two-dimensional dipole is discussed, in particular, the regime of chaotic dipole motion, which arises ...

Hidden momentum and the Abraham-Minkowski debate [PDF]
Phys. Rev. A 95, 043804 (2017), 2016 We use an extended version of electrodynamics, which admits the existence of magnetic charges and currents, to discuss how different models for electric and magnetic dipoles do or do not carry hidden momentum under the influence of external electromagnetic fields.
