Toward a Robust Estimate of the Solar Photospheric Poynting Flux and Helicity Flux
The Astrophysical JournalThe observed solar photospheric magnetic fields and Doppler velocities are frequently used to quantify the Poynting flux and helicity flux. Multiple methods have been developed for this purpose, but their estimates of the Poynting flux and helicity flux ...

Full three-dimensional Poynting vector flow analysis of great field-intensity enhancement in specifically sized spherical-particles [PDF]
, 2019 The Poynting vector plays a key role in electrodynamics as it is directly related to the power and the momentum carried by an electromagnetic wave. Based on the Lorenz-Mie theory, we report on the focusing effect of a spherical particle-lens by properly ...

The Poynting Vector In Laguerre-Gaussian Laser Modes
, 1995 It is found that the rotation of the Poynting vector of a Laguerre-Gaussian laser mode is proportional to the Gouy phase and for most cases of interest, rotates through less than one revolution in reaching the far field.

Electrodynamics in Euclidean Space Time Geometries
Open Physics, 2019 In this article it is proven that Maxwell’s field equations are invariant for a real orthogonal Cartesian space time coordinate transformation if polarization and magnetization are assumed to be possible in empty space. Furthermore, it is shown that this

What Can DKIST/DL-NIRSP Tell Us about Quiet-Sun Magnetism?
The Astrophysical JournalQuiet-Sun regions cover most of the Sun's surface; their magnetic fields contribute significantly to solar chromospheric and coronal heating. However, characterizing the magnetic fields of the quiet Sun is challenging due to their weak polarization ...

Maxwellian theory of gravitational waves and their mechanical properties
New Journal of Physics, 2014 We present a theory in Maxwellian form for gravitational waves in a flat background. This requires us to identify the gravitational analogues of the electric and magnetic fields for light.

Fast Poynting-Vector based wave-mode separation and RTM in 2D elastic TI media
, 2019 The wave-modes in isotropic elastic media are easy to get separated by using Helmholtz decomposition. This method, however, fails in TI (transverse isotropic) media due to the anisotropy, and more sophisticated operators are required.

Determination of Poynting Vector Characteristics
This paper presents a novel method for measuring the Poynting vector characteristics of monochromatic electromagnetic waves. We outline a specific design for such a meter and provide experimental data to validate the approach. For testing purposes, we utilized vortex beams with both linear and circular polarization.

Anomalous optical forces on a Mie-particle in a transverse Poynting vector flow
, 2012 We show how a superposition of non-interfering plane waves can generate a transverse Poynting vector, which in turn leads to transverse optical forces on a fully isotropic dielectric scatterer, in contrast with conventional radiation-pressure forces ...
