This is Pouria Zamzam. I am working on THz modern meta-atoms or metamatrials in Adelaide University. When it comes to metamarials in THz regime we mean periodic engineered structures which cannot be found in nature. They have attracted the attention of researchers since 2005 thanks to the unique and strange behaviors they have exhibited. This sphere is separated into to eras: 1. Old era which concentrates more on the negative refractive index materials and split ring resonators with the application of cloaking and absorption for energy harvesting and some limited medical issues like sensing. 2. Modern era which is called modern meta-photonics and it more concentrates on nano photonic resonators with high light-matter interaction engineering with high qualities with the application of high Q-factor THz sensors. I am working on Bound States in the Continuum (BICs), a new class of ultra-high-Q resonances that confine electromagnetic waves while remaining embedded in the radiation continuum. These states enable extremely sensitive THz sensing and low-loss light–matter interaction for next-generation meta-photonic devices.
