Abstract
The present paper conducts a scientific review on ionospheric absorption, extrapolating the research prospects of a complex eikonal model for one-layer ionosphere. As regards the scientific review, here a quasi-longitudinal (QL) approximation for nondeviative absorption is deduced which is more refined than the corresponding equation reported by Davies (1990). As regards the research prospects, a complex eikonal model for one-layer ionosphere is analyzed in depth here, already discussed by Settimi et al. (2013). A simple formula is deduced for a simplified problem. A flat, layered ionospheric medium is considered, without any horizontal gradient. The authors prove that the QL nondeviative amplitude absorption according to the complex eikonal model is more accurate than Rawer’s theory (1976) in the range of middle critical frequencies.
本文对电离层吸收进行了科学综述,并对单层电离层的复杂电离层模型的研究前景进行了推断。关于科学回顾,这里推导了一个准纵向(QL)近似的无偏差吸收,它比Davies(1990)报告的相应方程更精细。关于研究前景,本文深入分析了Settimi et al.(2013)已经讨论过的单层电离层的复杂eikonal模型。对一个简化的问题推导出一个简单的公式。考虑一个平坦的、分层的电离层介质,没有任何水平梯度。证明了在中临界频率范围内,基于复eikonal模型的QL无偏振幅吸收比Rawer理论(1976)更精确。
