Regarding the nonuniform plasma plate as uniform multilayer slabs, the total wave energy reflectance of the interface between the plasma before a conductor plate and the atmosphere or vacuum can be calculated by applying the equivalent input impedance method. The result obtained is that the reflection characteristics are affected by electron number density, plasma thickness, frequency and transmitting direction of the incident wave. Changing any factor of them, the total wave energy reflectance can be reduced greatly. In the low frequency band, the d istribution of electron number density almost does not affect the reflectance. B ut in the high frequency band, it will affect the reflectance. The effect of pla sma thickness, wave frequency, electron number density distribution on it is alm ost independent of the wave polarizing direction.
