Introduction In electromagnetics we need indicators for how a field, whether a scalar or a vector, changes within a segment of space or integrates over that segment. In this chapter we present three operators for such purposes: gradient, divergence, and curl. The gradient provides a measure of how a scalar field changes. For vector fields we use the divergence and the curl. For convenience, we may start with the Cartesian coordinate system. (However, …
