Abstract: The conclusion is analyzed and deduced again, which was presented in the reference that the phase constant and amplitude attenuation constant of electromagnetic wave satisfies constant relation when the inhomogeneous electromagnetic wave propagates in same and homogeneous conductive medium. Based on the boundary conditions of electromagnetic wave at the interface of conductive media, the expression of phase constant, amplitude attenuation constant and the sine of the angle between two constants and the interface normal are derived under two conditions. The results show that the phase constant and attenuation constant of electromagnetic wave doesn＇t satisfy constant relation when the electromagnetic wave propagates in same conductive medium, generally speaking.

Key words: inhomogeneous electromagnetic wave, phase constant, amplitude attenuation constant
