Computes reflectance (Rp/Rs) for surface plasmon resonance on a system of thin films

File Information
Description

Computes ratio of p-polarized reflectance to s-polarized reflectance (Rp/Rs) for surface plasmon resonance experiments. Uses multilayer matrix transfer method for a system of thin films. Works for any number of layers over any angle and frequency range. Includes data for some common substrates and conductors.

Default behaviour is so-called "fourier-transform" SPR, which outputs an entire frequency-intensity spectrum at each angle, but can easily be changed to "laser" SPR which scans over angles at a fixed frequency.

To use, open input_xphase.m in Matlab and follow the instructions inside. Once it runs, your reflectance data Rp/Rs is stored in variable R_mat, which you can plot in your favorite plotting program.
