where LJ 1 and q are given by Eqs. ( 5.21 ) and ( 5.34 ). In deriving Eqs. ( 5.177 )
and ( 5.178 ) we have neglected the terms which contain the factor .V AI =c/ 2

Applying a Bessel transform to Eqs. ( 5.130 ) and ( 5.131 ) one can express the
components of electromagnetic field through the potentials. The derivatives @ z
