There’s a well-worn pattern in the development of AI chatbots. Researchers discover a vulnerability and exploit it to do ...

We often think of memories like the contents of a museum: static exhibits that we view to understand the present and prepare for the future.

Abstract: This work presents a reconfigurable one-bit phase-coded metamaterial based on effective medium theory, providing a solution for dynamic broadband electromagnetic (EM) scattering manipulation ...

Abstract: A method of designing a two-bit ultra-wideband phase-coded reflective metamaterial is presented and used for further electromagnetic (EM) scattering manipulation. First, the anisotropic ...
