DOI: 10.1088/1402-4896/acd3bc

Abstract: Switchable and tunable broadband perfect absorbers have drawn great interest in a wide range of applications, including modulation, energy harvesting, and spectroscopy. Here, we propose a switchable and tunable terahertz (THz) metamaterial absorber with dual-broadband,… read more here.

DOI: 10.1088/1674-1056/ac0794

Abstract: A tunable metamaterial absorber (MA) with dual-broadband and high absorption properties at terahertz (THz) frequencies is designed in this work. The MA consists of a periodic array of flower-like monolayer graphene patterns at top, a… read more here.

recommendations! Published in 2019 at "IEEE Microwave and Wireless Components Letters"

DOI: 10.1109/lmwc.2019.2902725

Abstract: This letter proposes a novel in-band digital predistortion technique to linearize the concurrent dual-broadband phased array transmitters, which can remove the in-band distortion with reduced processing bandwidth compared to conventional methods. Based on $1\times 4$… read more here.

DOI: 10.1364/ome.8.003104

Abstract: In this paper, we present a novel design of a dual and broadband metamaterial absorber (MMA) based on a compact meander wire structure resonator in the terahertz (THz) region. The simulation results indicate that the… read more here.
