Computer processing of plasmon tomography images
A method to analyze Surface Plasmon Polaritons (SPP) has been commonly used in recent years known as SPP Tomography. This method allows for the creation of back focal plane (BFP) images when thin metals are used for SPP structures. It is the purpose of this paper to discuss the necessary information imparting the knowledge of how one can analyze the BFP images and utilize necessary programming skills in order to create a better method of properly doing this analysis. By allowing creating a Mathematica program that is user friendly those who need to analyze these structures will then have a tool that is useful, which may be more accurate, and quick. A few BFP examples of hexagonal and square lattices are used to test the accuracy of the program that was developed. These structures were fabricated with a known crystal period, and numerical aperture, which allows for calculated comparisons for accuracy. By making this comparison the success of the program is established.
