Conference Proceeding
Leach, A., Rudden, L. S., Bond-Taylor, S., Brigham, J. C., Degiacomi, M. T., & Willcocks, C. G. (2020). Shape tracing: An extension of sphere tracing for 3D non-convex collision in protein docking. In 2020 IEEE 20th International Conference on Bioinformatics and Bioengineering (BIBE) (49-52). https://doi.org/10.1109/bibe50027.2020.00016

This paper presents an algorithm, similar to implicit sphere tracing, that ray marches 3D non-convex shapes for efficient collision detection. Instead of finding points on the surface where individual rays strike, an entire shape is marched in unison...

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.

In Proceedings of the 33rd International Conference on Infrared, Millimeter, and Terahertz Waves: 15-19 September 2008, Pasadena, California (496-497). https://doi.org/10.1109/icimw.2008.4665668

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..
