Metasurfaces, the two-dimensional counterpart of metamaterials, enable an unprecedented capability in manipulating the phase, polarization and amplitude of electromagnetic waves. Here, we have ...

India’s ambitious Samudrayaan mission is gearing up for a crucial phase, as the National Institute of Ocean Technology (NIOT) prepares to conduct a second series of harbour tests in Chennai. The ...

With the growing demand for sustainable energy solutions and self-powered sensing devices, triboelectric nanogenerators (TENGs) have gained considerable attention due to their ability to efficiently ...

Electrostatic interactions in systems composed of finite-sized dielectric materials extend well beyond simple point-charge approximations, particularly when many-body polarization effects become ...

A novel polarization-reconfigurable aperture-coupled magnetoelectric (ME) dipole antenna is presented. By electronically controlling the state of switches between square patches and an additional ...

University of Waterloo researchers have revealed the exact scenario necessary to make a sphere roll down a vertical plane without physical intervention. While this niche observation might seem ...
