| Description |
This code computes the complex dielectric constant (i.e. relative permittivity) and the refractive index of various metals using either the Lorentz-Drude (LD) or the Drude model (D) as a function of input light wavelength.
Additionally, it may compute the dielectric constant of pure water using a Debye-Lorentz model.
Choice of materials: silver, aluminum, gold, copper, chromium, nickel, tungsten, titanium, beryllium, palladium, platinum, triply distilled water.

Added some small changes to improve the overall performance. Included a screenshot to show the comparison between the Drude, Lorentz-Drude and exact experimental values of the permittivity of silver. |
| 27 Nov 2008 |
Added a new material (pure water) whose dielectric constant is computed via the Debye-Lorentz model. References are also updated. |
| 01 Dec 2008 |
A coding error in the previous version is corrected in this version. |
