Accidental Bragg Reflectors

Mentor: Zachary Holman
FURI: Spring 2019

When creating thermal insulating films, it was discovered that they produce colors. Since the films had layers, it was concluded that they were acting as Bragg reflectors- mechanisms with layers of varying refractive indices that produce colors. To determine if these can be replicated purposely, it first was necessary to see if the films could be modeled. Using a computer program called MacLeod, the films’ properties such as layer thickness and refractive index could be modified based on the measured transmission. Bragg reflectors have many purposes such as lasers and the internet. Enhancing the creation process could improve their applications.

S.H.E.I.L.D. Particulate Coatings

Mentor: Zachary Holman
FURI: Fall 2018

This research aims to produce a coating that will allow single paned windows to have a better transmittance while maintaining the same haze as dual pane windows. This will increase the thermal and acoustic comfort of buildings. Through criteria set by the SHIELD (Single-Pane Highly Insulating Efficient Lucid Designs) project, the researchers aim to optimize the particulate coating by using porous silica on silicon wafers.
