beams.rotation_matrix

Computes a rotation matrix that arbitrarily reorients a field.

The rotation operations consist of,

• rotation about the y-axis by polar_angle
• rotation about the z-axis by azimuthal_angle
• rotation about propagation axis by polarization_angle, where the propagation axis is found by applying the first two rotations about the y- and z-axis.

Args:

• polar_angle: The rotation angle about the y-axis.
• azimuthal_angle: The rotation angle about the z-axis.
• polarization_angle: The rotation angle about the propagation axis.

Returns:

• None: The rotation matrix.
