The Hong Kong University of Science and Technology (HKUST)-led research team has adopted gyromagnetic double-zero-index ...

Researchers advance 3D and 4D printed electromagnetic metamaterials (EMMs) - enabling the production of next-generation ...

The combination of 3D and 4D printing technologies with EMMs holds great promise for the future, driving innovation and opening up new avenues for research and development in multiple disciplines.

Abstract: A design technique for lossless surface invisibility cloaks for free-space objects using surface waves is presented. For a time-harmonic plane wave of known incidence direction and ...

“This is no invisibility cloak,” Hamish de Bretton-Gordon, a former British Army colonel and chemical weapons expert, told The Telegraph. “In fact, because of the contrast, it makes them mor ...

We condemn oppression, whoever commits it." Alawites trying to survive physically and identity-wise under Syria's war shadow face similar invisibility in Turkey. Sectarian prejudices, political ...

Abstract: Devices like invisibility cloaks are designed based on the method of transformation optics, which have anisotropic inhomogeneous structures. In this paper, we examine uniqueness of the ...
