The basic method of electric field measurement, over a wide frequency range, involves the use of charge induction phenomenon in a body illuminated by the field. As shown in Fig. 4.1 is the electromotive force (emf) e_E induced by the electric component of the EMF generated by an arbitrary source in a symmetrical dipole antenna of total length 2h.
