What is a Metamaterial, and Why Should You Care?
Why I’m Writing This # Between 2017 and 2018, I started a PhD candidature in acoustic metamaterials at the University of Adelaide. The research focus was nonlinear acoustic metamaterials with chaotic spring responses for low-frequency sound suppression. It ended at the 12-month review, a combination of inadequate supervision, gaps in my own mathematical background, and a research environment that didn’t quite set me up for success. I left feeling frustrated and, honestly, a bit defeated.
