One of the most significant discoveries in recent years can be the invention of a fundamentally new material that has the ability to change the characteristics of sound signals. With it, you can direct, form and focus sound waves that pass through it. The new find will make revolutionary transformations in the field of medical research, in the creation of acoustic devices. The uniqueness of such types of materials called metamaterials consists in an unusual internal structure and does not depend on the chemical composition.
Researchers of Sasekx and Bristol Universities were able to present a very clear experiment showing the possibilities of new materials. The metamaterial demonstrated in the form of discrete units of “blocks” was lined in a plane in one layer, and sound vibrations passing through the lined plane were transformed in such a way that they forced to steam a small object above the surface – a foam ball.
The head of the acoustic laboratory of the Sussex University, Dr. Sriram Subramanian, indicates that the direction in the study of the possibilities of comprehensive control of sound waves remains a priority, giving acoustic fluctuations of all kinds of sizes necessary for the user. The sound will also be easy to control, as now control light in liquid crystalline screens. Such a discovery will allow revolutionary transformations in medicine in the field of diagnosis and treatment of various internal diseases, to have an effect on the tumors.
