Micro-Doppler is regarded as a unique signature of a target with micro-motions. The
sophisticated recognition of the cone-shaped targets can be realized through the micro …

Free-space optical (FSO) communication has gained much interest due to its capability of
providing not only a cost-efficient solution where the optical fiber is too expensive or too …

Laguerre–Gaussian (LG) beam scattering by a perfect electromagnetic conductor (PEMC)
cylinder coated with a metamaterial is analyzed. In order to obtain the LG beam scattering …

Orbital angular momentum (OAM) radars are able to estimate the azimuth angle and the
rotation velocity of multiple targets without relative motion or beam scanning. Moreover …

Orbital angular momentum (OAM) at radio frequency (RF) provides a novel approach of
multiplexing a set of orthogonal modes on the same frequency channel to achieve high …

Radar imaging can provide important information of target for recognition. However, due to
the limited azimuth resolution, it is difficult to improve the imaging quality of the existing …

Radio orbital angular momentum (OAM) communications require accurate alignment
between the transmit and receive beam directions. Accordingly, a key feature of OAM …

In the millimeter-wave (mm-Wave) multiuser-multiple-input multiple-output (MU-MIMO)
system, the interferences among different users generally degrade the system performance …

In this paper, a double-layer acoustic metasurface (DAM) composed of a fixed lower
acoustic metasurface (LAM) and a rotatable upper acoustic metasurface (UAM) is proposed …

This study examines the scattering of the orbital angular momentum (OAM) carrying wave by
perfect electromagnetic conductor (PEMC) sphere. The incident and scattered …
