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)

Assumptions:
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)
