In the book of Tesche,Ianoz, Karlsson "Analysis Methods and Computational Models" I've found the formula for calculating E-field of a dipole in a point (look at the attachment)
Please? explain me the next moments:
1. As I've understood, the real part of the expression is accorded with the amplitude of the radiated field, and the virtual - with the phase. I'm interested only ion the amplitude. So how should the formula look like in this case.
2. This formula is for the dipole, oriented along the Z-axis. How should it be changed for the arbitrarily oriented dipole?
3. How should I change this formula, to set the measure point in Cartesian coordinates?
Thanks in advance!
