Maxwell's wave equation
WebThe vector wave equation admits, in the paraxial limit, of a family of localized Bessel–Gauss beam solutions that can describe the entire transverse electric field. Two … WebBut the first of Maxwell’s equations says that the divergence of E is ρ / ϵ0. Inserting this equality in Eq. ( 18.4 ), we get back Eq. ( 18.2 ), which we know is true. Conversely, if we accept Maxwell’s equations—and we do because no one has ever found an experiment that disagrees with them—we must conclude that charge is always conserved.
