Expressions for power reflection ( R ), transmission ( T ) and absorption ( A ) coefficients for p ‐polarized wave for a warm, collisional, magnetized and moving plasma slab (with sharp boundaries and thickness d 0 ) are investigated. The effects of plasma slab velocity (β= v/c ), electron density (ω p /ω) 2 and plasma temperature ( K B T ) on reflection ( R ), transmission ( T ) and absorption ( A ) coefficients are discussed numerically. It is observed that for the value β=−0.6, reflection coefficient ( R ) becomes more than unity, whereas absorption coefficient ( A ) becomes quite negligible while transmission coefficient ( T ) shows oscillatory behaviour. The variation with plasma frequency (ω p /ω) 2 shows that at lower plasma frequency (ω p /ω) 2 =0.2 transmission ( T ) and absorption ( A ) coefficients are minimum while reflection coefficient ( R ) is maximum.
