Quasi-Optical Terahertz Polarizers Enabled by Inkjet Printing of Carbon Nanocomposites Arindam Das Thomas Schutzius Constantine M. Megaridis 10027/10796 https://indigo.uic.edu/articles/journal_contribution/Quasi-Optical_Terahertz_Polarizers_Enabled_by_Inkjet_Printing_of_Carbon_Nanocomposites/10957088 We report a new approach for cost-effective manufacturing of THz quasi-optical polarizers by inkjet printing of polymer-carbon nanowhisker (CNW) dispersions. The electromagnetic interference properties of coatings with fixed CNW/polymer composition and varying thickness are quantified by a frequency domain THz spectroscopy system in the range 570-630GHz. A shielding effectiveness of ~40dB is attained for 70m-thick coatings. A prototype THz polarizer printed on Mylar film displayed transmission and absorbance that varied with polarization orientation. The degree of polarization for film thickness of ~1μm was 0.35. This performance can be improved by refining grid dimensions, increasing coating thickness and adopting multi-layer polarizer structures. 2013-12-03 00:00:00 untagged
