treams.cw.rotate

treams.cw.rotate(kz, mu, pol, qz, m, qol, phi) = <ufunc 'rotate'>

Rotation coefficient for cylindrical modes.

Returns the correct rotation coefficient or a combination thereof for the specified mode. A basis does not have to be specified since the coefficients are the same in helicity and parity modes.

Parameters:

• kz (float, array_like) – Z component of the destination mode

• mu (int, array_like) – Order of the destination mode

• pol (int, array_like) – Polarization of the destination mode

• qz (float, array_like) – Z component of the source mode

• m (int, array_like) – Order of the source mode

• qol (int, array_like) – Polarization of the source mode

• phi (float, array_like) – Rotation angle

Returns:
