ABSTRACT
This chapter discusses the propagation of plane waves. The Fresnel reflection coefficients are derived and expressed in various forms which depend on the way that the propagation constant is defined. The topics of reflection and transmission from a dielectric and from a lossy region are included. Other topics covered in this chapter are the Zenneck, lateral, trapped waves and plane wave reflection and transmission from interfaces. A discussion of plane waves in various regions where the dielectric and conductivity changes as a function of position (i.e., inhomogeneous regions) is presented for both rectangular and cylindrical regions. This chapter ends with a discussion of the WKBJ method for both normal and oblique incidence.
