Reflection of the transitional electromagnetic wave by inhomogeneous ionized media having a peak of electron density

The reflection coefficient of an inhomogeneous ionized medium having a peak in electron density is analysed. The result shows the existence of peak influences for the phase term of non-peak linearly varying electron density in the medium. The characteristic of the reflection coefficient phase delay versus frequency is related to the electron density at a peak point and the position of the electron peak. Using this theory we can obtain the electron density distribution map in the inhomogeneous ionized medium. To verify the theory the reflection coefficient is compared with the results from the finite difference time domain method; both results give a good agreement.
