ABSTRACT
When a plane electromagnetic wave is obliquely incident on a dielectric boundary, there are particular angles of incidence leading to a condition of total reflection. The critical angle is given by arcsin ( ϵ 2 / ϵ 2 ) 1 / 2 https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315272351/41040b79-9956-496a-ac34-683fa4364729/content/eqi14e_4.jpg"/> , and, thus, total reflection is not possible from an optically denser medium [1]. The situation for the case of two relatively moving dielectric media was examined by Shiozawa and Kumagai [2]. If the wave traveling in free space is incident on a plasma medium, total reflection can take place under certain conditions; at normal incidence, waves of frequency less than the plasma frequency are totally reflected [3], and, for oblique incidence, the range of wave frequencies for total reflection is generally extended [4]. The purpose of this appendix was to investigate how this frequency range is modified by the motion of the plasma medium that may be isotropic or uniaxially anisotropic. Both parallel and perpendicular polarizations of the obliquely incident wave are considered. A few workers [5–7] have also touched upon total reflection in a limited manner in their treatment of reflection and transmission of electromagnetic waves from moving media.
