The Radiance of Objects in Place,A gradient is the vectorial magnitude of a scalar. For example, the scalar (Ф) which at point P has coordinates x,y,z, takes on a value Ф(x,y,z). By definition, at the point P (see Figure 1.1), the gradient of Ф is given by a vectorial magnitude, as in: . Ф(x,y,z), which is such that .

Optimal Control and Identification ProblemsHaving looked at the way in which electromagnetic (EM) waves are emitted by a particle accelerating in a vacuum in Chapter 9, this chapter is concerned with how EM waves interact with materials, and in particular:
