Revisiting optical absorption power density of inhomogeneous plane waves
Results in OpticsWe review the analytical expressions for the complex Poynting’s vector in the case of arbitrary plane-waves in a lossy isotropic medium. We demonstrate how these expressions can be used to recover the optical absorption power density Q, considering the ...

Scattering forces on magneto-dielectric particles and the electromagnetic momentum density
Advanced Electromagnetics, 2013 In this paper we analyze the non-conservative forces on magneto-dielectric particles in special configurations where the scattering force is not proportional to the average value of the Poynting vector.

The Poynting Vector and Angular Momentum of Airy Beams
Frontiers in Optics 2008/Laser Science XXIV/Plasmonics and Metamaterials/Optical Fabrication and Testing, 2008 We analyze and describe the evolution of the Poynting vector and angular momentum of the Airy beam as it propagates through space. A numerical approach is used to show the Poynting vector follows the tangent line of the direction of propagation. A similar approach is used to show that while the total angular momentum of the Airy beam is zero, the ...

Energy and momentum flux in a high-numerical-aperture beam using the extended Nijboer-Zernike diffraction formalism [PDF]
Journal of the European Optical Society-Rapid Publications, 2007 We describe the energy and momentum flux in the case of an aberrated optical imaging system with a high numerical aperture (NA). The approach is based on the extended Nijboer-Zernike diffraction theory, that, in its high-NA version, yields an accurate ...

Study on measurement of Poynting vector distributions of radio waves
, 2020 電子機器等から放射される高周波（GHz帯）電磁波のポインティングベクトル（エネルギーの流れ）の空間分布を計測する手法を開発した。メタサーフェス構造を利用することで、電磁界ベクトルの2次元分布計測センサを考案し、ポインティングベクトル分布計測・可視化システムを構築した。また電磁波ノイズ源周辺におけるポインティングベクトルの振る舞いを詳細に解析し、波源から放射された電磁界エネルギーがどのように伝搬し、センサに結合して計測されるかを調べた。A novel measurement technique was ...
