Recently, a research team led by Prof. Huang Zhulin from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences successfully synthesized a flexible nanofiber felt with ultralow ...

Electromagnetic metamaterials with negative physical parameters such as negative dielectric constant and negative magnetic ...

Electromagnets with iron cores are used: in scrap yards to lift magnetic materials such as iron and steel; to separate magnetic materials such as iron and steel from non-magnetic materials ...

Professor Fuli Zhang's team pioneered the first millimeter-wave low-profile cross-shaped conformal programmable metasurface. This innovative design adopts a radiation-type programmable surface ...

Count the number of paper clips held by each material. Record in a table and compare results. Iron and steel make strong electromagnets. The current increases. The number of turns in the coil ...
