Contrast and resolution enhancement in a confocal terahertz video system. (2008)
Journal Article
Zinov’ev, N., Adrianov, A., Gallant, A., Chamberlain, J., & Trukhin, V. (2008). Contrast and resolution enhancement in a confocal terahertz video system. JETP Letters, 88(8), 492-495. https://doi.org/10.1134/s0021364008200058

The effect of image contrast enhancement without the loss of the spectral composition of the radiation under investigation has been experimentally demonstrated for a terahertz far-field video system. The result has been obtained by using a confocal a... Read More about Contrast and resolution enhancement in a confocal terahertz video system..

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...

Negative refraction can make non-diffracting beams (2008)
Journal Article
Kaliteevski, A., Brand, S., Abram, R., Gallant, A., & Chamberlain, J. (2008). Negative refraction can make non-diffracting beams. Optics Express, 16(19), 14582-14587. https://doi.org/10.1364/oe.16.014582

We report the results of simulations relating to the illumination of a structure consisting of a slab constructed from a 2-D hexagonal array of metal rods with a terahertz frequency source. As a consequence of negative refraction an essentially non-d... Read More about Negative refraction can make non-diffracting beams.

Tamm plasmon polaritons: Slow and spatially compact light (2008)
Journal Article
Sasin, M., Seisyan, R., Kaliteevski, M., Brand, S., Abram, R., Chamberlain, J., …Kavokin, A. (2008). Tamm plasmon polaritons: Slow and spatially compact light. Applied Physics Letters, 92(25), Article 251112. https://doi.org/10.1063/1.2952486

We report on the first experimental observation of Tamm plasmon polaritons (TPPs) formed at the interface between a metal and a dielectric Bragg reflector (DBR). In contrast to conventional surface plasmons, TPPs have an in-plane wavevector less than... Read More about Tamm plasmon polaritons: Slow and spatially compact light.

Terahertz filter based on refractive properties of metallic photonic crystal (2008)
Journal Article
Kaliteevski, M., Brand, S., Garvie-Cook, J., Abram, R., & Chamberlain, J. (2008). Terahertz filter based on refractive properties of metallic photonic crystal. Optics Express, 16(10), 7330-7335. https://doi.org/10.1364/oe.16.007330

We propose a new type of pass-band filter, in this case designed to operate in the terahertz frequency regime, possessing two separate pass-bands utilizing the distinction between positive and negative refraction in a photonic crystal prism. The pris... Read More about Terahertz filter based on refractive properties of metallic photonic crystal.
