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.

Effect of Wood’s Anomalies on the THz Transmission Spectra of Free- Standing Metallic Hole Arrays (2015)
Presentation / Conference Contribution
Hill, C., Klein, A., Balocco, C., Wood, D., & Gallant, A. (2015, December). Effect of Wood’s Anomalies on the THz Transmission Spectra of Free- Standing Metallic Hole Arrays. Presented at 2015 40th International Conference on Infrared, Millimeter, and Terahertz waves (IRMMW-THz), Hong Kong, China

A free-standing periodic array of subwavelength rectangular apertures has been designed to exhibit peak transmission which is dominated by localized aperture resonance in the THz region. By varying the incident angle, Wood's anomalies can be introduc... Read More about Effect of Wood’s Anomalies on the THz Transmission Spectra of Free- Standing Metallic Hole Arrays.

3D polymer structures with variable permittivity at terahertz frequencies (2015)
Presentation / Conference Contribution
Hammler, J., Pan, Y., Gallant, A., & Balocco, C. (2015, August). 3D polymer structures with variable permittivity at terahertz frequencies. Presented at 2015 40th International Conference on Infrared, Millimeter, and Terahertz waves (IRMMW-THz), Hong Kong, China

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 con...

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...
