pymiediff.coreshell.nearfields(k0, r_probe, r_c, eps_c, r_s=None, eps_s=None, eps_env=1.0, E_0=1, backend='torch', precision='double', which_jn='recurrence', n_max=None)#

near fields in and around core-shell particles

Results are retured as a dictionary with keys:

  • ‘E_i’: incident E-field

  • ‘H_i’: incident H-field

  • ‘E_s’: scattered E-field

  • ‘H_s’: scattered H-field

  • ‘E_t’: total E-field

  • ‘H_t’: total H-field

Parameters:

  • k0 (_type_) – _description_

  • r_probe (_type_) – _description_

  • r_c (_type_) – _description_

  • eps_c (_type_) – _description_

  • r_s (_type_, optional) – _description_. Defaults to None.

  • eps_s (_type_, optional) – _description_. Defaults to None.

  • eps_env (float, optional) – _description_. Defaults to 1.0.

  • E_0 (int, optional) – _description_. Defaults to 1.

  • backend (str, optional) – _description_. Defaults to “torch”.

  • precision (str, optional) – _description_. Defaults to “double”.

  • which_jn (str, optional) – _description_. Defaults to “recurrence”.

  • n_max (_type_, optional) – _description_. Defaults to None.

Returns:

contains incident, scattered and total E- and H-fields

Return type:
