Negative refracting materials at THz frequencies. (2008)
Presentation / Conference Contribution
Swift, G. P., Gallant, A. J., Dai, D., Kaliteevski, M. A., Brand, S., Zeze, D. A., Wood, D., Petty, M. C., Abram, R. A., & Chamberlain, J. M. (2008, December). Negative refracting materials at THz frequencies. Presented at 33rd International Conference on Infrared, Millimeter, and Terahertz Waves, Pasadena, CA

We demonstrate here, for the first time, the construction of artificial materials, which theoretically possess two separate pass-bands utilizing the difference between positive and negative refraction in the terahertz frequency regime. Experimental t... Read More about Negative refracting materials at THz frequencies..

Micromachined Terahertz Waveguides with Embedded Metal Rods (2008)
Presentation / Conference Contribution
Gallant, A., Baragwanath, A., Swift, P., Wood, D., & Chamberlain, M. (2008, December). Micromachined Terahertz Waveguides with Embedded Metal Rods. Presented at 33rd International Conference on Infrared, Millimeter, and Terahertz Waves, Pasadena, CA

In this paper we report on a novel fabrication approach for the manufacture of terahertz waveguides with embedded metal rods. It is anticipated that this type of structure could be used for sub-wavelength imaging or as a method to effectively couple...

Flexible polymer based artificial materials for terahertz applications. (2007)
Presentation / Conference Contribution
Gallant, A., Zeze, D., Wood, D., Petty, M., Dai, D., & Chamberlain, J. (2007, December). Flexible polymer based artificial materials for terahertz applications. Presented at Joint 32nd International Conference on Infrared and Millimeter Waves, 2007 and the 2007 15th International Conference on Terahertz Electronics. IRMMW-THz., Cardiff, Wales

In this paper we report on the fabrication and testing of arrays of subwavelength apertures which are formed in a highly flexible polymer, PDMS (polydimethylsiloxane). PDMS can be elastically stretched to cause the deformation of any surface features... Read More about Flexible polymer based artificial materials for terahertz applications..

Passband filters for terahertz radiation based on dual metallic photonic structures (2007)
Journal Article
Gallant, A., Kaliteevski, M., Wood, D., Petty, M., Abram, R., Brand, S., …Chamberlain, J. (2007). Passband filters for terahertz radiation based on dual metallic photonic structures. Applied Physics Letters, 91(16), https://doi.org/10.1063/1.2800381

This paper reports on the development of two-dimensional metallic microstructures for the filtering of terahertz radiation. These structures are fabricated using ultraviolet-based processing of thick SU8 resist. This micromachining technique enables...
