Abstract: This article presents a wideband dB-linear variable-gain amplifier (VGA) with a compensated negative pseudo-exponential generation (C-NPEG) technique for high-speed applications. By shifting the concave and the convex function of an original negative pseudo-exponential generator (NPEG),… read more here.

Abstract: We propose a bi-layer transmissive metasurface to obtain linear-to-circular polarization conversion in a wideband. The unit cell of each metasurface layer, which has identical configuration, consists of a Jerusalem-cross-like resonator and a metal strip. A… read more here.
