Scattering of spoof surface plasmon polaritons in defect-rich THz waveguides (2019)
Journal Article
Klein, A. K., Basden, A., Hammler, J., Tyas, L., Cooke, M., Balocco, C., …Gallant, A. (2019). Scattering of spoof surface plasmon polaritons in defect-rich THz waveguides. Scientific Reports, 9(1), Article 6288. https://doi.org/10.1038/s41598-019-42412-6

We report on the first observation of ‘Spoof’ Surface Plasmon Polariton (SPP) scattering from surface defects on metal-coated 3D printed, corrugated THz waveguiding surfaces. Surface defects, a result of the printing process, are shown to assist the... Read More about Scattering of spoof surface plasmon polaritons in defect-rich THz waveguides.

Machinable ceramic for high performance and compact THz optical components (2018)
Journal Article
Klein, A. K., Hammler, J., Balocco, C., & Gallant, A. J. (2018). Machinable ceramic for high performance and compact THz optical components. Optical Materials Express, 8(7), 1968-1975. https://doi.org/10.1364/ome.8.001968

The properties of Shapal Hi-M Soft, an aluminum nitride based ceramic, as a material for THz optical components are investigated and compared with other ceramic materials. Shapal is a low-cost and machinable ceramic with a high-refractive index and l... Read More about Machinable ceramic for high performance and compact THz optical components.

Effect of Wood’s Anomalies on the THz Transmission Spectra of Free- Standing Metallic Hole Arrays (2015)
Conference Proceeding
Hill, C., Klein, A., Balocco, C., Wood, D., & Gallant, A. (2015). Effect of Wood’s Anomalies on the THz Transmission Spectra of Free- Standing Metallic Hole Arrays. In 2015 40th International Conference on Infrared, Millimeter, and Terahertz waves (IRMMW-THz), Hong Kong, 2015. https://doi.org/10.1109/irmmw-thz.2015.7327803

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.
