Abstract

The analytical form of absorption index appropriate to a certain range of height of the upper atmosphere plasma medium during ordinary wave propagation under quasi-transverse approximations has been utilized to develop an integral equation through Wentzel-Kramers-Brillouin method of solution. The integral equation is useful for the determination of effective electron collision frequency. Numerical results are presented graphically along with the results of some earlier work.

Keywords
