An orbital energy flow and a spin flow at the tight focus
نویسندگان
چکیده
We have shown that a reverse energy flow (negative projection of the Poynting vector onto optical axis) at sharp focus an vortex with topological charge 2 and left-hand circular polarization arises because axial spin has negative axis is greater in magnitude than positive orbital (canonical flow). Also, using Richards-Wolf formulas, it when focusing left-handed circularly polarized light, region on-axis flow, light right-handed polarized.

Orbital rotation without orbital angular momentum: mechanical action of the spin part of the internal energy flow in light beams.
The internal energy flow in a light beam can be divided into the "orbital" and "spin" parts, associated with the spatial and polarization degrees of freedom of light. In contrast to the orbital one, experimental observation of the spin flow seems problematic because it is converted into an orbital flow upon tight focusing of the beam, usually applied for energy flow detection by means of the me...
متن کاملPseudo Steady State Gas Flow in Tight Reservoir under Dual Mechanism Flow
Gas reservoirs with low permeability (k<0.1 mD) are among the unconventional reservoirs and are commonly termed as "Tight Gas Reservoirs". In conventional gas reservoirs that have high permeability, the flow of gas is basically controlled by the reservoir permeability and it is calculated using the Darcy equation. In these reservoirs, gas flow due to gas diffusion is ignored compared to Dar...
متن کاملThe Minimum Universal Cost Flow in an Infeasible Flow Network
In this paper the concept of the Minimum Universal Cost Flow (MUCF) for an infeasible flow network is introduced. A new mathematical model in which the objective function includes the total costs of changing arc capacities and sending flow is built and analyzed. A polynomial time algorithm is presented to find the MUCF.
متن کاملTransverse energy flow at HERA
We calculate the transverse energy flow accompanying small x deepinelastic events and compare with recent data obtained at HERA. In the central region between the current jet and the remnants of the proton we find that BFKL leading ln(1/x) dynamics gives a distinctively large transverse energy distribution, in approximate agreement with recent data. The structure function F2(x,Q ) for deep-inel...

1.0 overview it seems that grammar plays a crucial role in the area of second and foreign language learning and widely has been acknowledged in grammar research. in other words, teaching grammar is an issue which has attracted much attention to itself, and a lot of teachers argue about the existence of grammar in language teaching and learning. this issue will remind us a famous sentence f...
