What is it about?

Imagine if you could create materials that can bend, block, or absorb sound waves in ways that ordinary materials can’t. That’s the idea behind metamaterials, a type of artificial material that has been studied for over 20 years. But how far have we come in turning this idea into reality? In this article, we focus on one type of metamaterial that can absorb sound very well and show how it can be customized for different purposes. We also look at some examples of how this technology has been used in real-life situations and give you a glimpse of the current state of metamaterials in the market.

Why is it important?

We examined how metamaterials can be tailored to specific needs while obeying the laws of physics and how this flexibility enables them to be used in various products that can be mass-produced.


This article has given me a chance to reflect on and share the years of efforts that I and my co-authors and colleagues have made to discover the potential of metamaterials. I am delighted to be part of such a fast-moving field.
