A numerical solution of the wave equations for whistler electromagnetic waves incident on the ionosphere from above is obtained. For the calculations, we used a matrix algorithm for the approximate solution of wave equations in a stratified smoothly inhomogeneous medium and the collocation method for solving the boundary problem. Dependences of reflection coefficients R are obtained and analyzed on the frequency and angle of incidence of the wave for different seasons and time of day. At night, for waves with frequencies from 1 to 10 kHz, the values of R vary from 0.1 to 0.7. In daytime conditions, the value of R, on average, is two orders of magnitude lower and does not exceed 0.04. The smallest values of the reflection coefficient are associated with waves, the reflection of which occurs in the region of strong attenuation at heights of 80–110 km. The results obtained explain the specific features of the conditions for the excitation of the plasma magnetospheric maser.
