Editing Cloaking device (section)

===Cloaking in mechanics===
The concepts of cloaking are not limited to optics but can also be transferred to other fields of physics. For example, it was possible to cloak acoustics for certain frequencies as well as touching in mechanics. This renders an object "invisible" to sound or even hides it from touching.<ref>{{ cite journal | last = Bückmann | first = Tiemo | year = 2014 | title = An elasto-mechanical unfeelability cloak made of pentamode metamaterials | journal = [[Nature Communications]] | volume = 5 | issue = 4130 | pages = 4130 | doi = 10.1038/ncomms5130 | pmid = 24942191 | bibcode = 2014NatCo...5.4130B | doi-access = free }}</ref>
