نویسندگان
چکیده
A freely tunable polarization rotator for broadband terahertz waves is demonstrated using a three-rotating-layer metallic grating structure, which can conveniently rotate the polarization of a linearly polarized terahertz wave to any desired direction with nearly perfect conversion efficiency. This low-cost, high-efficiency, and freely tunable device has potential applications as material analysis, wireless communication, and THz imaging.

متن کاملGiant tunable Faraday effect in a semiconductor magneto-plasma for broadband terahertz polarization optics.
We report on a giant Faraday effect in an electron plasma in n-InSb probed via polarization-resolved terahertz (THz) time-domain spectroscopy. Polarization rotation angles and ellipticities reach as large as π/2 and 1, respectively, over a wide frequency range (0.3-2.5 THz) at magnetic fields of a few Tesla. The experimental results together with theoretical simulations show its promising abili...

In this paper, a compact plasmonic metamaterial absorber for terahertz frequencies is proposed and simulated. The absorber is based on metamaterial graphene structures, and benefits from dynamically controllable properties of graphene. Through patterning graphene layers, plasmonic resonances are tailored to provide a dual band as well as an improved bandwidth absorption. Unit cell of the design...

متن کاملBroadband THz reflective polarization rotator by multiple plasmon resonances.
We demonstrate a metamaterials-based THz broadband polarization rotator which is able to rotate linearly polarized THz wave by 90 degree within a wide frequency range (0.44 to 0.76 THz). The device is characterized both theoretically and experimentally. Analyses show that the multiple-plasmon-resonance is the key for the broadband feature and the phase-shift difference of the two reflection com...
