註釋

For purposes of electronic countermeasures, it is desirable to maximize the amount of power that can be transmitted from a reentry vehicle by supppressing the onset of antenna voltage breakdown. This can be accomplished by injecting chemicals into the reentry plasma sheath. The report describes a numerical procedure for calculating the amount of power that can be transmitted through a chemically seeded plasma. The power levels of a plane electromagnetic wave incident on a reentry plasma slab are sufficient to induce electron temperature changes. As a result, the electron density and effective collision frequency vary with time. (Author).
