In wireless communication systems, a multibeam can be used to increase the number of
spatial channels by space-division multiplexing. Furthermore, the multimode is used to …

In this work, we propose and realize a smart metasurface for programming electromagnetic
(EM) manipulations based on human speech recognition. The smart metasurface platform is …

Because of the shortcomings associated with their scattering patterns, both the chessboard
and cubic phased metasurfaces show non-perfect diffusion and hence sub-optimal radar …

This letter presents a novel circular leaky-wave antenna (CLWA) on a half-mode inter-
digitated capacitor based corrugated substrate integrated waveguide (HM-IDC-CSIW) to …

Orbital angular momentum (OAM) beams, also known as vortex beams, have gained a
significant attraction in the past decade. Their ability to offer an infinite number of modes …
