One of the most fascinating examples of such structures is negative-index metamaterials (NIMs). The emergence of optical metamaterials opens up fundamentally new regimes of light–matter interaction and prompts unique opportunities for manipulating light and has given rise to numerous unusual linear and...
These artificially structured composites, known as metamaterials, have the potential to fill critical voids in the electromagnetic spectrum where material response is limited and enable the construction of novel devices. Recently, metamaterials that display negative refractive index – a property not found...
The authors demonstrate a magnetic-field-controlled, on-off switchable non-reciprocal negative refractive index in a non-Hermitian photon-magnon hybrid system, highlighting the crucial role of non-Hermitian dynamics in advancing photonics and magnonics in quantum hybrid technologies. ...
Numerical simulations of wedgeand triangle-shaped metamaterials are used to prove the negative refractive index of the models. The fabricated MTMs exhibit passband characteristics which are in good agreement with the model results. The parametric studies of correlated factors further support these ...

Sometimes they alternate tiny layers to produce a substance with a negative refractive index that bends light in unexpected directions. In theory, such material could cloak an object by making light waves pass around it and then continue along their original straight paths, so the object would be...
