A Discussion of the Wheeler-Feynman Absorber Theory of Radiation

A Discussion of the Wheeler-Feynman Absorber Theory of Radiation PDF Author: Ronald G. Newburgh
Publisher:
ISBN:
Category : Absorption
Languages : en
Pages : 34

Book Description
The Wheeler-Feynman absorber theory of radiation is reviewed. A proof is offered to show that a sum of advanced and retarded effects from the absorber can provide the origin of radiative reaction. This proof is different from and perhaps simpler than that of Wheeler and Feynman. From arguments of momentum and energy conservation the necessity of the absorber for the emission of radiation is demonstrated for three cases. (Author).

Hydromagnetic Ionizing Waves

Hydromagnetic Ionizing Waves PDF Author: Allen G. Rubin
Publisher:
ISBN:
Category : Electromagnetic waves
Languages : en
Pages : 26

Book Description
A theory of hydromagnetic ionizing waves has been developed which is valid in the region in which gas pressure is negligible, compared with magnetic pressure. The theory takes into account the energy expended in partial ionization of the gas behind the wave. The usual high conductivity boundary condition behind the wave is not employed. The electric field in front of the wave is taken as a parameter. Results of this theory are compared with available experimental measurements, and show good agreement. (Author).

The Theoretical and Numerical Determination of the Radar Cross Section of a Finite Cone

The Theoretical and Numerical Determination of the Radar Cross Section of a Finite Cone PDF Author: F. V. Schultz
Publisher:
ISBN:
Category : Boundary value problems
Languages : en
Pages : 14

Book Description
In this work, rigorous electromagnetic theory is used to determine the nose-on radar cross section of a perfectly conducting cone of finite height. The end cap of the cone is assumed to be a segment of a s spherical surface with center at the apex of the cone. Numerical results have been obtained for a cone having a total apex angle of 30 degrees and for values of [kappa alpha] ranging from 0.0259 to 5.18, where [kappa]=2 [pi]/[lambda] and [alpha] is the radius of the base of the cone. Siegel's Rayleigh method and by using Keller's modified geometrical optics as well as with experimental results obtained by Keys. The comparisons are instructive below [kappa alpha] = 3.2, the apparent upper limit of validity of the present results -- p.[3].
