Angular Distribution of Intensity of Resonance Radiation

Angular dependence of synchrotron radiation intensity

The detailed analysis of angular dependence of the synchrotron radiation (SR) is presented. In particular, we analyze the angular dependence of the integral SR-intensity and peculiarities of the angular dependence of the first harmonics SR. Studying spectral SR-intensities, we have discovered their unexpected angular behavior, completely different from that of the integral SR-intensity. Namely,...

Nanoscale shift of the intensity distribution of dipole radiation.

The energy flow lines (field lines of the Poynting vector) for radiation emitted by a dipole are in general curves, rather than straight lines. For a linear dipole the field lines are straight, but when the dipole moment of a source rotates, the field lines wind numerous times around an axis, which is perpendicular to the plane of rotation, before asymptotically approaching a straight line. We ...

Real-time display of radiation field intensity distribution.

A real-time display system has been designed and tested for use with a radiation field monitor. The system uses only pulse and waveform generators, a multiplexer, and an oscilloscope. The display consists of either a three-dimensional representation of the field intensity distribution or a series of simultaneous profiles.

Angular correlations of galaxy distribution

We study the angular correlations of various galaxy catalogs (CfA1, SSRS1, Perseus-Pisces, APM Bright Galaxies and Zwicky). We find that the angular correlation exponent is γ a = 0.1 ± 0.1 rather than γ a = 0.7 as usually found by the standard correlation function ω(θ). We identify the problem in the artificial decay of ω(θ). Moreover we find that no characteristic angular scale is present in a...
