Occam's razor redux: A simple mathematical approach to designing mechanical invisibility cloaks

Metamaterials – engineered materials with properties not found in nature – have led to an astounding range of optical, acoustic, thermodynamic, two-dimensional solid mechanics, and other types of invisibility cloaks that ...

No Hogwarts invitation required: Invisibility cloaks move into the real-life classroom

Who among us hasn't wanted to don a shimmering piece of fabric and instantly disappear from sight? Unfortunately, we non-magical folk are bound by the laws of physics, which have a way of preventing such fantastical escapes.

Here's what it feels like to be invisible – less anxious

Recent advances with so-called meta-materials have shown that a practical invisibility cloak might one day be possible. But a new study has approached the scenario from the other direction, asking what it would feel like ...

Mechanical cloaks of invisibility—without complicated mathematics

A honeycomb is a very stable structure. If it has a larger hole, however, stability is largely lost. What might a honeycomb look like, which survives external forces in spite of a hole? Such stable types of known constructions ...

Scientists create invisible objects without metamaterial cloaking

Âé¶¹ÒùÔºicists from ITMO University, Ioffe Institute and Australian National University managed to make homogenous cylindrical objects completely invisible in the microwave range. Contrary to the now prevailing notion of invisibility ...

Intermediary neuron acts as synaptic cloaking device

Neuroscientists believe that the connectome, a map of each and every connection between the millions of neurons in the brain, will provide a blueprint that will allow them to link brain anatomy to brain function. But a new ...

Engineering discovery brings invisibility closer to reality

Since the beginning of recorded time, humans have used materials found in nature to improve their lot. Since the turn of this century, scientists have studied metamaterials, artificial materials engineered to bend electromagnetic, ...

Study shows way to design 'digital' metamaterials

Metamaterials, precisely designed composite materials that have properties not found in natural ones, could be used to make light-bending invisibility cloaks, flat lenses and other otherwise impossible devices.

Multiphysics invisibility cloak manipulates both electric current and heat

Invisibility cloaks can make objects invisible not just to light in the visible part of the spectrum, but to many other physical excitations. These include acoustic waves, matter waves, heat flux, and infrared or ultraviolet ...
