pymiediff.special.vsh(n_max, k0, n_medium, r, theta, phi, kind, epsilon=1e-08)#

vector spherical harmonics for l=1

Parameters:

  • n_max (int) – Maximum evaluation order (all up to this will be returned)

  • k0 (torch.Tensor) – vacuum wavenumber

  • n_medium (torch.Tensor) – refractive index of medium

  • r (torch.Tensor) – radial coordiantes

  • theta (torch.Tensor) – polar angle coordinates

  • phi (torch.Tensor) – azimuthal angle coordinates

  • kind (int) – radial dependence. 1: j_n, 2: y_n, 3: h1_n.

  • epsilon (float, optional) – small numerical value to avoid singularity at origin. Defaults to 1e-8.

Raises:

ValueError – _description_

Returns:

_description_

Return type:

_type_
