The next-generation wireless technology that can fulfill such a demand, namely the fifth-
generation (5G) technology, should provide 1000 times larger capacity. Moreover, sixth …

Electromagnetic (EM) vortex can realize high resolution imaging in forward-looking
observation geometry without relative motion between the radar system and targets …

We identify that flexural guided elastic waves in elastic pipes carry a well-defined orbital
angular momentum associated with the compressional dilatational potential. This enables …
