摘要
Results are presented of theoretical investigations of the nature of nondeviative radio‐wave absorption at vertical incidence, in an isothermal ionospheric region where collisional frequency is comparable to the exploring frequency and where the recombination coefficient is not constant but is a function of height. It has been shown that in such cases the variation of nondeviative absorption with solar zenith angle and frequency may be represented by the expression:L ∝ {(cosX)π/(ω±∣ωL∣)C+n}where symbols have their usual meaning. The values of n and C are such that (2 — C) ≥ n ≥ 0 and 3/2 ≥ C ≥ 1/2. Copyright 1969 by the American Geophysical Union.
