A design of the low-pass filter using the novel microstrip defected ground structure
TL;DR: In this article, a new defected ground unit structure (DGS) for the microstrip line is proposed, which can provide the bandgap characteristic in some frequency bands with only one or more unit lattices.
Journal ArticleDOI
Advances in terahertz communications accelerated by photonics
TL;DR: In this paper, the state-of-the-art technologies on photonics-based terahertz communications are compared with competing technologies based on electronics and free-space optical communications.
Journal ArticleDOI
Capacity bounds and power allocation for wireless relay channels
Anders Host-Madsen,Junshan Zhang +1 more
TL;DR: Compared to the direct transmission and traditional multihop protocols, the results reveal that optimum relay channel signaling can significantly outperform multihip protocols, and that power allocation has a significant impact on the performance.
Journal ArticleDOI
Reflection-free one-way edge modes in a gyromagnetic photonic crystal.
TL;DR: It is shown that the TM modes in a gyromagnetic photonic crystal can be formally mapped to electronic wave functions in a periodic electromagnetic field, so that the only requirement for the existence of one-way edge modes is that the Chern number for all bands below a gap is nonzero.
Journal ArticleDOI
Realizing effective magnetic field for photons by controlling the phase of dynamic modulation
Kejie Fang,Zongfu Yu,Shanhui Fan +2 more
TL;DR: By considering a resonator lattice in which the coupling constants between the resonators are harmonically modulated in time and by controlling the spatial distribution of the modulation phases, the authors introduced a scheme that can generate an effective magnetic field for photons, without the use of magneto-optical effects.
