Appendix 14E: On Total Reflection of Electromagnetic Waves from Moving Plasmas*

Dikshitulu K. Kalluri and R.K. Shrivastava

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 (ϵ2/ϵ2)1/2, 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 ...
