Multipath interference disrupts wireless signals, causing issues like TV ghosting and fading. Now, researchers have developed a passive metasurface that overcomes traditional filtering limits. Using a ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

As the number of higher-throughput applications grows, so does the need for a wider bandwidth and network coverage in wireless systems. Given limited spectrum allocation, wireless communication ...

Interoperable multipath hemispherical map (MHM) using overlap-frequency signals across constellations. The top panel shows the flowchart for modelling and correcting multipath in interoperable MHM.

Today, many wireless communications systems incorporate multiple input, multiple output (MIMO) antenna schemes to take advantage of the multipath signal propagation. In addition, many of today’s ...

This video presents a study in which researchers developed a passive metasurface that uses a time-varying interlocking mechanism with metal-oxide-semiconductor field-effect transistors to selectively ...
