Free-space material characterisation at terahertz frequencies using a vector network analyser (2015)
Presentation / Conference Contribution
Hammler, J., Gallant, A., & Balocco, C. (2015, December). Free-space material characterisation at terahertz frequencies using a vector network analyser. Presented at URSI AT-RASC 2015, Gran Canaria, Spain

While dielectric properties of many materials have been extensively characterised at low frequencies and into the microwave region of the electromagnetic spectrum, published information is much sparser in the THz region. Knowledge of permittivity is... Read More about Free-space material characterisation at terahertz frequencies using a vector network analyser.

3D polymer structures with variable permittivity at terahertz frequencies (2015)
Presentation / Conference Contribution

Simple de-embedding and simulation technique to find permittivity with a THz vector network analyser (2015)
Presentation / Conference Contribution
Hammler, J., Gallant, A., & Balocco, C. (2015, August). Simple de-embedding and simulation technique to find permittivity with a THz vector network analyser. Presented at 2015 40th International Conference on Infrared, Millimeter, and Terahertz waves (IRMMW-THz), Hong Kong, China

A simple and fast method for measuring the dielectric constant with a THz vector network analyser (VNA) has been developed. A numeric de-embedding technique removes free-space propagation effects, then simulation of Maxwell's equations simultaneously...
