Chapter 1 (sec. 1.4.5) includes an introduction to the polarization dependencies of the reflection coefficient for a smooth, flat surface and to the effects of multipath propagation. The present appendix includes equations and example calculations for reflection coefficients of smooth and rough earth surfaces. Furthermore, equations are given for calculating the pattern propagation factor F for both flat earth and spherical earth geometries. In addition, the SM that accompanies this book provides examples using Mathcad for calculating reflection coefficients and the pattern propagation factor F. Therefore, by changing the initial assumptions, the user may readily attain computer calculated solutions to a wide variety of problems involving reflections applicable to either flat earth or spherical earth geometries.
