Poynting vector for Cauchy-Riemann beams
We present a detailed derivation of the Poynting vector for Cauchy-Riemann beams propagating in free space considering a Gaussian modulation with $g \in \mathbb{C}$. The effect generated by this Gaussian modulation is a compression-expansion of the intensity distribution.

Behaviour of the Poynting vector in absorbing chiral media
, 2000 The Poynting vector behaviour in chiral media with losses is studied. It is found that its mean temporal value has a component which is not on the incidence plane, while the instantaneous vector moves along the lateral surface of a cone which has its ...

About the Rejection of Poynting Vector in Power Systems Analysis
, 2007 This article is a response to a paper presented at the sixth International Workshop on Power Definitions, a report that rejected the fact that the Poynting vector (PV) provides useful information “for academic interpretation of power properties and for ...

Poynting Vector Analysis of Synchronous Generators Using Field Simulations
IEEE Transactions on Magnetics, 2007 The Poynting vector has been used to gain an understanding of energy flow in rotating electrical machines. Previous studies of energy flow in rotating electrical machines have used the Poynting vector in crude formulas to obtain a qualitative picture. In
