Permittivity of Metals at Optical Wavelengths (Brendel-Bormann)

Relative complex permittivity of various metals using the Brendel-Bormann method.

Description

Calculate the relative complex permittivity of various common metals over all possible optical wavelengths using the Brendel-Bormann method as cited by A.D. Rakic, et. al., App. Opt., vol. 37, no. 22, 1998.

Supported metals:
- Silver (Ag)
- Gold (Au)
- Copper (Cu)
- Aluminum (Al)
- Beryllium (Be)
- Chromium (Cr)
- Nickel (Ni)
- Palladium (Pd)
- Platinum (Pt)
- Titanium (Ti)
- Tungsten (W)

Requires the complex error function matlab file 'cef.m' (included) in order to run, originally coded by A. Weideman, and available for direct download here: http://dip.sun.ac.za/~weideman/research/cef.html

This file must be left in the same directory as the parent file 'eps_BB.m'.

• MATLAB release: MATLAB 7.5 (R2007b)

Very useful for Surface Plasmon Polariton modeling if one chooses to fit various FDTD package's (meep, lumerical, etc.)permittivity functions to data than to look up and translate the necessary components from handbooks.

Thank you.
