This program computes the following optical properties of a single nanowire with up to 2 shell layers using Mie-formalism:
1) Total scattering, absorption and extinction efficiency
2) Absorption efficiency of individual layers
3) The integrated photon flux absorbed and the ideal photocurrent density under AM 1.5 G illumination as a function of layer thickness
4) Electric and magnetic polarizability under TE polarization (E field perpendicular to nanowire axis)

1) Nanowires are infinitely long which is valid as long as the nanowire length is > 10*diameter.
2) Incident light is a plane-wave whose angle of incidence can be defined. Two polarizations are considered: Case I (H field is perpendicular to the nanowire axis) and Case II (E field is perpendicular to the nanowire axis). Unpolarized response is calculated as an average of Case I and Case II.
Note: When the illumination is incident normal to the nanowire axis, Case I corresponds to transverse magnetic (TM) and Case II corresponds to transverse electric (TE)
