“…Serious theoretical difficulties are encountered when attempting to separately consider L and S for the electromagnetic fields ( [7], [8] On the other hand, the total integrated value of the angular momentum of the electromagnetic field, expressed here in convenient units as an integral over all space involving the electric and magnetic fields E(r) and B(r)…”

“…Ohanian [14] treated the angular momentum by expressing the magnetic field as the curl of the vector potential and decomposing the latter, but his method has the disadvantage of not being gauge invariant. Barnett and Allen [15] assumed an azimuthal phase dependence of one particular form. Barnett [16] applied the concept of angular momentum flux arising from the conservation laws of classical field theory to monochromatic waves of specified azimuthal phase dependence but did not treat the boundary conditions necessary to resolve the plane wave issue.…”

“…Пучки Бесселя имеют орбитальный угловой мо-мент [7,8]. Суперпозиция пучков Бесселя может об-ладать продольной периодичностью (аналог эффекта Тальбота) [9,10] или вращаться вокруг оптической оси при распространении [11,12].…”

“…Недавно открытые пучки Ханкеля-Бесселя [24] могут приме-няться для зондирования атмосферы, так как обладают устойчивостью к турбулентности атмосферы [25]. В [26,27] теоретически были рассмотрены векторные пучки Бесселя, для которых были получены аналити-ческие выражения для плотности ОУМ [7,8,28]. Заме-тим здесь, что, так как энергия всего пучка Бесселя не ограничена, полный ОУМ тоже не ограничен.…”
