The electrical conductivity of weakly ionized gases(
Book
)
1 edition published in 1962 in English and held by 1 WorldCat member library worldwide
Some elementary solutions of the wave equation are obtained for electromagnetic waves in an ionized gas. The solutions demonstrate the importance of conductivity in controlling absorption. Improper computation of conductivity by conventional theory may lead to order of magnitude errors in estimating absorption. The theory of A.C. conductivity for a weakly ionized gas is reviewed. It is shown when and how the exact theory may be employed in conventional form and without error. The expression for the conductivity of a weakly ionized mixture of gases is formulated and analyzed in the low, intermediate and high pressure regions. The conductivity of the mixture is shown to be reducible to the sum of conductivities of gases of constant cross section but complex wave frequencies. Appropriate tables for the evaluation of these latter conductivities are being constructed. (Author)

The energy electron in a gas in an arbitrary electric field i(
Book
)
1 edition published in 1956 in English and held by 1 WorldCat member library worldwide
The average energy of electrons in a gas in an arbitrary electric field is determined from the time dependent Boltzman transport equation. The assumptions are: collision frequencies are dependent of energy and there are only elastic collisions. The solution is obtained for the case of a sinusoidally varying field and contrasted with a solution obtained on a more elementary level. (Author)

The nonlinear propagation of strong electromagnetic waves through weakly ionized media(
Book
)
1 edition published in 1959 in English and held by 1 WorldCat member library worldwide
This paper presents a theoretical treatment of the nonlinear propagation of strong electromagnetic waves through weakly ionized water vapor. It shows that when the parameters of propagation are held within certain constraints, analytical solutions may be obtained which describe the amplitude of such waves. These solutions are applied to the question of propagation through rocket exhaust gases. A novel method is described for altering the attenuation experienced by a signal sent from the ground, through the exhaust gases, to the missile. This is accomplished by broadcasting a powerful 'sacrificial' wave from the missile to alter the electrical characteristics of the exhaust. (Author)

GRAPHS OF THE REAL AND IMAGINARY PARTS OF THE EFFECTIVE COLLISION FREQUENCY FOR WEAKLY IONIZED AIR(
)
1 edition published in 1962 in English and held by 0 WorldCat member libraries worldwide
Graphs of the real and imaginary parts of the effective collision frequency for air are presented. The propagation constants for an E.M. wave propagating in ionized air with a static magnetic field are presented in terms of these effective collision frequencies. A numerical example illustrating the use of these graphs is presented
