One example is the connection between temporal symmetry and energy conservation: if a physical system is described by laws that do not explicitly depend on time, its total energy must be preserved.

For example, metamaterials have unique properties because they interact with forces at the nanoscale in ways that we can only explain by using quantum mechanics.

The human eye, for example, measures reflection of sunlight from objects, and radar observes reflection off radar waves from objects. The same objects made of metamaterials could achieve near-zero ...

These nonreciprocal metamaterials can potentially be used to realize new types of mechanical devices: for example, actuators (components of a machine that are responsible for moving or controlling ...

Step aside, nanotechnology, the buzzword for todays material scientist is "metamaterials." These substances are tiny engineered structures from existing composite that are used to manipulate light ...

Theory for metamaterials that act as an analog computer Date: January 9, 2014 Source: University of Pennsylvania Summary: A new study shows that metamaterials can be designed to do "photonic ...

The final example deals with the use of digital metamaterials in demonstrating the supercoupling phenomenon present in the epsilon-near-zero (ENZ)-filled narrow channels connecting two 2D parallel ...

A new technique involving complementary metamaterials allows high-frequency acoustic waves used in ultrasound to penetrate bone and metal by negating the properties of the so-called aberrating layers.

Due to their unusual ability to manipulate electromagnetic waves and their potential to be harnessed for technology (that might, for example, cloak objects from view), negative-index metamaterials ...

A super-material that bends, shapes and focuses sound waves that pass through it has been invented by scientists. The creation pushes the boundaries of metamaterials - a new class of finely ...

Lord Patrick Vallance said metamaterials would be "everywhere" in the future [University of Exeter] The University of Exeter is getting £19.6m of funding to improve our lives with "brand new ...
