What is it about?
Calculating the transport of light and electricity in random structures is a difficult problem that has been studied for a long time. In this article, we unified and extended existing techniques to show how to efficiently and progressively use more geometrical information to obtain tighter constraints on estimates. We applied this to a simple model for random structures, showing an obvious way to estimate how much these polarize when stretched.

Why is it important?
Random materials are quite common but it's generally difficult to calculate how they transport light and electricity. This article combines several methods into one that is relatively fast and gives significant insight into general principles of transport in polarizing structures.

I enjoyed developing this fantastic technique with PhD student Marc Gali.
