3D polymer structures with variable permittivity at terahertz frequencies.

Hammler, J. and Pan, Y. and Gallant, A.J. and Balocco, C. (2015) '3D polymer structures with variable permittivity at terahertz frequencies.', in 40th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), 23-28 August 2015, Hong Kong. Piscataway: IEEE, pp. 1-2.


Titanium dioxide (TiO2) powder has been blended with polydimethylsiloxane (PDMS) to manufacture a composite polymer with variable permittivity. Vector network analyser measurements taken between 0.75-1.1 THz quantify the relationship between TiO2 concentration and complex permittivity of the resultant material. Complex 3D structures have been produced with a casting process. Applications for the tunable-permittivity polymer include dielectric regions in photonic and plasmonic devices operating at terahertz frequencies as well as single pixel imaging systems.
