Poynting Vector of Complex Optical Fields

Frontiers in Optics 2013, 2013
Poynting vector density of polarization singular field with well defined polarization structure such as lemon or star is experimentally measured using polarization interference and found to have unique features in contrast to constituent scalar fields.

Poynting’s Vector. Comments on a Recent Paper by C. Jeffries

SIAM Review, 1994
Summary: The comments concern the paper [\textit{C. Jeffries}, ibid. 34, No. 4, 386- 405 (1992; Zbl 0759.35047)]. Poynting's theorem, and the use of Poynting's vector to express the transfer of energy from one part of the system to another in terms of the electric field \(E\) and the magnetic field \(H\) are shown to follow directly from Maxwell's ...

Where is the Poynting vector in an ideal transformer?

American Journal of Physics, 1984
A simple calculation is presented verifying consistency of the Poynting theorem with the result of elementary circuit theory, in regard to the power flow across an ideal transformer. It is found that a nonzero Poynting vector is inevitably accompanied by certain departures from ideal behavior. Nonetheless, the use of ideal-transformer circuit relations

Energy in Electromagnetism: The Poynting Vector

2017
John Henry Poynting (1852–1914) [Figure 1(a)] was born in Lancashire, England, and he was the youngest son of Thomas Elford Poynting, a Unitarian minister who was also the teacher in the local school Poynting where he attended when he was young. Poynting later attended Owens College in Manchester, England (1867–1872), where he studied physics under the

The Critical Points of Poynting Vector Fields

1988
In a thought provoking paper Maxwell [The Scientific Papers of James Clerk Maxwell, ed. W. D. Niven, vol. 2, 233-240, Dover Publications, New York (1952)] studied the flow of water on the Earth's surface and how this flow is affected by the local geography.
