We report a LiDAR transmitter incorporating both a hybrid-integrated tunable external cavity
laser and a high-resolution 2-D optical phased array beam-steerer. Widely tunable single …

This work presents a parallel-plate waveguide (PPWG) fanbeam antenna achieving a field
of view with an average maximum scan loss of over the Ka-band for a flat feed surface. This …

Intelligent reflecting surface (IRS) is one of the promising technologies for next-generation
communication systems. Although IRS can enhance the integrity of the transmitted signal …

Controlling objects with body language is an extremely interesting ability for human beings.
Recognizing different gestures is an effective way to collect valuable information, which is …

In this article, a time-modulated transparent nonlinear active metasurface loaded with
varactor diodes was proposed to realize spatial electromagnetic (EM) wave frequency …

This work describes a procedure to analyze the impedance and transmission of an active
three-layer unit cell considering the interlayer coupling. Using the unit cell full wave …

Abstract Millimeter wave (MMW) GRadient INdex (GRIN) lens antennas leverage spatially
varying refractive structures to generate high directivity beams. GRIN lenses also …

This paper describes a compact circularly polarized antenna designed for the 2.4 GHz band
with a gain of 15dBi. The proposed antenna upgraded a standard short backfire antenna …
