Parity-time symmetric chain resonators (2016)
Presentation / Conference Contribution
Phang, S., Vukovic, A., Creagh, S., Gradoni, G., Sewell, P., & Benson, T. M. Parity-time symmetric chain resonators. Presented at 7th International Conference on Metamaterials, Photonic Crystals and Plasmonics (META 16)

A simple tight-binding model to study the band-structure of an infinite length Parity-time (PT) symmetric chain of resonators is presented in this paper. In the talk, we will investigate the impact of having a structure of finite length and consider... Read More about Parity-time symmetric chain resonators.

Experimental benchmarking of Unstructured Transmission Line Modelling (UTLM) method in modelling twisted wires (2016)
Journal Article
Meng, X., Sewell, P., Rahman, N. H., Vukovic, A., & Benson, T. M. (in press). Experimental benchmarking of Unstructured Transmission Line Modelling (UTLM) method in modelling twisted wires

In this paper the Unstructured Transmission Line Modelling (UTLM) method based on a tetrahedral mesh has been applied to modelling of the coupling between a single wire and a twisted wire pair. The effects of wire twisting on the crosstalk and coupli... Read More about Experimental benchmarking of Unstructured Transmission Line Modelling (UTLM) method in modelling twisted wires.
