Wave normal and Poynting vector calculations using the Cassini radio and plasma wave instrument
Wave normal and Poynting vector measurements from the Cassini radio and plasma wave instrument (RPWS) are used to examine the propagation characteristics of various plasma waves during the Earth flyby on August 18, 1999. Using the five-channel waveform receiver (WFR), the wave normal vector is determined using the Means method for a lightning-induced whistler, equatorial chorus, and a series of...
متن کاملPulse centroid velocity of the Poynting vector.
The evolution of the pulse centroid velocity of the Poynting vector for both ultrawideband rectangular and ultrashort Gaussian envelope pulses is presented as a function of the propagation distance in a dispersive, absorptive dielectric material. The index of refraction of the material is described by the Lorentz-Lorenz formula in which a single-resonance Lorentz model is used to describe the m...
متن کاملGravitational Analog of the Electromagnetic Poynting Vector
The gravitational analog of the electromagnetic Poynting vector is constructed using the field equations of general relativity in the Hilbert gauge. It is found that when the gravitational Poynting vector is applied to the solution of the linear mass quadrupole oscillator, the correct gravitational quadrupole radiation flux is obtained. Further to this, the Maxwell-like gravitational Poynting v...
متن کاملThe Poynting vector in Laguerre-Gaussian laser modes
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. For a p=O mode, we show the expression for the rotation is particularly simple and independent of 1. At the radius corresponding to maximum intensity, it yields a rotation of o...
متن کاملAbout Poynting vector in axially symmetric stationary spacetimes
We dispose of some objections raised by Manko et al. [2] on a recently published paper on the role of Poynting vector in the ocurrence of vorticity in electrovaccum spacetimes [1]. In order to confirm the Bonnor’s hyphothesis about the role of the electromagnetic energy flux as the responsible for the vorticity in the surrounding of non–rotating sources of some gravitational fields [3], Herrera...
