A theory of ionospheric thermal radiation
(Elsevier, 1966-08)
The ionosphere is considered as a dissipative medium in which the random thermal motions of the charged particles act as a source of thermal radiation. Attention has been focused on the electrons colliding with ions and ...
Fluorescence as a source of noise in Q-switched ruby laser atmospheric backscattering experiments
(Elsevier, 1969-06)
Interpretation of the results of atmospheric baekscattering experiments, when using a Q-switched ruby laser as the source of photons, requires consideration of several sources of noise in the statistical analysis. This ...
Non-adiabatic motion of charged particles traversing a weak magnetic field: Pitch angle scattering
(Birkhäuser-Verlag; Birkhäuser Verlag ; Springer Science+Business Media, 1964-12)
A charged particle moves with velocity v in a constant non-uniform magnetic field H , spiralling with Larmor radius R . If R is small compared with the scale length L of the field, the magnetic moment associated with the ...
Effect of longitudinal electrostatic field on the whistler mode propagation in a warm magneto-ionic medium
(Elsevier, 1968-02)
The dispersion equation for a whistler mode propagation in a warm plasma, subjected to parallel static electric and magnetic fields, is derived by using a linearized coupled Vlasov-Maxwell equation. From the derived ...
Characteristics of ionospheric thermal radiation
(Elsevier, 1966-08)
A theoretical observation of the characteristics of ionospheric thermal radiation is made using a linear theory, based on a macroscopic concept with the aid of fluctuating electromagnetic field theory. The thermal noise ...
On the development of baroclinic waves influenced by friction and heating
(Birkhäuser-Verlag; Birkhäuser Verlag ; Springer Science+Business Media, 1967-12)
The influence of surface skin friction and a specific type of heating on the stability of baroclinic waves in a two-level, quasi-geostrophic model is investigated. It is found that the effect of friction alone changes the ...
Whistler mode propagation in the ionosphere in the presence of a longitudinal static electric field
(Elsevier, 1968)
The effect of a longitudinal electrostatic field on whistler mode propagation has been studied in a region of the ionosphere where the influence of particle collisions and ion motion may be significant. As an illustration, ...
Laser scatter measurements in the mesosphere and above
(Elsevier, 1969-01)
Recent papers by Sandford are discussed in relation to results from an improved optical radar which was in use during the period January-February 1967.
Cutoff conditions for transverse circularly polarized electromagnetic waves in a finite temperature electro-magneto-ionic medium
(Elsevier, 1967-10)
The dispersion relation for wave propagation in a homogeneous, electrically neutral electron gas subject to crossed static electric and magnetic fields is derived using the coupled Maxwell-Boltzmann-Vlasov equations. The ...
