Narrowband Signals and Phasor Fields,Consider a signal .(.) whose FT, .(ω) is of the type depicted in Fig. 4.1. The spectrum is concentrated near ω = 0. In the figure .(ω) is real (and even, see Section 3.2.1), but complex spectra can be considered, the only condition being tht |.(ω)|. is essentially . around ω = 0.

High-Frequency Fields,We consider a narrowband signal (see Chapter 4) in a lossless time-invariant isotropic medium of parameters ε.ε and μ.μ, whose relative permittivity ε and permeability μ may be space-dependent. We define the free-space propagation constant ., the free-space intrinsic impedance ., and the relative refractive index ., space-dependent in general.

There is no doubt that these solutions are very important because they shed light on the physics of the problem and are the necessary basis to understand more complicated situations. Concepts
