Appendix B
Vector Formulas
Although the material provided in Chapter 3 should be sufficient to manipulate any vector formula that will be encountered in antenna theory, it will be convenient to have a list of most commonly used vector formulas. A selection of these is presented in this appendix.
In the following we will make use of the vectors A, B and C and the scalars Φ and Ψ.
We start by writing the gradient, divergence and curl operations in rectangular coordinates:

B.2 
B.3 
Also

B.5 
A list of useful vector identities is given below:
