Current dominant system architectures for terahertz waves are adapted from other ranges, leading to critical bottlenecks. This project will address this with a new integration platform that is tailored to the particular needs of terahertz waves. This requires advances in the emerging field of micro-scale integrated optics, combined with antenna-theory principles, semiconductor science, and advanced microfabrication to incorporate active devices. Novel spatially-dependent dispersion engineering techniques will also be pioneered for phased-array-free beamforming. This will enable a broad variety of all-in-one handheld systems for practical applications of terahertz waves such as noninvasive standoff sensing and self-aligning wireless links.Read moreRead less

The Australian government has decided to support the timely rollout of fifth-generation (5G) mobile communication systems due to their potential for producing far-reaching economic and social benefits. This infrastructure rollout requires a quick, efficient deployment of the associated 5G base stations. The integration of 5G antenna arrays into existing 3G/4G base stations would alleviate the substantial cost increases and negative environmental impacts tied to acquiring new sites for them. This project aims to develop the theory and engineering methodologies necessary to successfully address the significant scientific challenges posed by the detrimental interference effects associated with the compact integration of 3G/4G/5G arrays.
