About

Created by David C. Heson, Jack Liu, and Dr. William M. Robertson over the 2022 MTSU Computational Sciences REU (NSF REU Award #1757493).

Codebase created to explore the optical properties of multilayers and optimize their design to achieve maximum sensibilities, using minimas of reflected light and RIU (Refractive Index Unit) as qualitative measurements. A new measurement called SWT (Shift With Thickness) was also introdued, which is defined as the degree or nanometer shift in the location of a Bloch Surface Wave when the bottom layer increases by 10 nanometers in thickness.

Currently, the entirety of the code is written in Python Anaconda 3-5.3.1.

Functionalities

The current functionalities of the program are:

• Input any custom multilayer arrangement into the existing functions, including ones to dynamic indexes of refraction values.
• Graph reflection and transmission coefficients across multilayers with changing angle or wavelength, for specific polarisation mode.
• Graph the electric field profile accross a multilayer for a specific angle, wavelength, polarisation, and multilayer.
• Calculate RIU and SWT values for specified multilayer arrangements.
• Explore by force bruting a set of parameters for the multilayers, finding the best setups in terms of RIU/SWT and reflectivity dips.
• Simulate the properties of a multilayer using a dynamic index of refraction, which is wavelength dependent and corresponds to a user-defined function.
• More to come!

To Do

• Rewrite matrix calculations using Rust.
• Explore how to do a gradient descent on parameter regions of interest.
• Improve help and context messaging.
• Condense and improve the electric field calculation.
