Vector spherical harmonics (Magnetic and electric multipoles, far-fields, until order n=3)
Магнитные(M) и электрические(N) векторные сферические гармоники. Для сравнения показаны также скалярные функции с теми же числами. n=1 соответствует диполям, n=2 - квадруполям и n=3 октуполям. Стрелками показаны направления электрического поля
