Metamaterials are carefully engineered materials that possess desirable properties and can be used to manipulate electromagnetic, acoustic, or other types of waves in interesting ways. Some materials ...
Acoustic metamaterials are a fast-evolving family of materials which manipulate sound waves in ever more advanced ways. Now, a team led by Changqing Xu at Nanjing Normal University in China has ...
This will vastly improve the ability to rapidly design metamaterials – exciting artificial materials used to amplify, block or deflect waves. The findings, published in the journal Proceedings of the ...
A metamaterial is any material that was engineered so that a property not found in naturally occurring materials could be exploited. Designed right, metamaterials can affect sound waves, ...
What exactly is the difference between "introduction to" and "introduction of"? For example: should it be "Introduction to the problem" or "Introduction of the problem"?
Introduction into is non-standard in Britain and (as far as I know) most of the US when used in a figurative sense (i.e. in the sense of making acquaintance with). Of course, one can introduce one physical object into another, or an idea into a conversation or intellectual construct: Jorge introduced the stick of the firework into the neck of the milk bottle.

McArthur’s point is similar to that in ‘Linguistics: An Introduction’ by Radford and others: ‘Sociolinguistic research has demonstrated that the speech of most people is, at least in some respects, variable, combining, for example, both standard and non-standard sounds, words or grammatical structures.’
