Neural-adjoint method for the inverse design of all-dielectric metasurfaces
Yang Deng, Simiao Ren, Kebin Fan +2
All-dielectric metasurfaces exhibit exotic electromagnetic responses, similar to those obtained with metal-based metamaterials. Research in all-dielectric metasurfaces currently us…
Frequency-tunable metamaterials using broadside-coupled split ring resonators
Evren Ekmekci, Andrew C. Strikwerda, Kebin Fan +3
We present frequency tunable metamaterial designs at terahertz (THz) frequencies using broadside-coupled split ring resonator (BC-SRR) arrays. Frequency tuning, arising from change…
Nonlinear terahertz metamaterials via field-enhanced carrier dynamics in GaAs
Kebin Fan, Harold Y. Hwang, Mengkun Liu +7
We demonstrate nonlinear metamaterial split ring resonators (SRRs) on GaAs at terahertz frequencies. For SRRs on doped GaAs films, incident terahertz radiation with peak fields of…
Manipulating THz Spin Current Dynamics by the Dzyaloshinskii-Moriya Interaction in Antiferromagnetic Hematite
Hongsong Qiu, Tom Sebastian Seifert, Lin Huang +12
An important vision of modern magnetic research is to use antiferromagnets as controllable and active ultrafast components in spintronic devices. Hematite is a promising model mate…
Extremely thin perfect absorber by generalized multipole bianisotropic effect
Hao Ma, Andrey B. Evlyukhin, Andrey E. Miroshnichenko +8
Symmetry breaking plays a crucial role in understanding the fundamental physics underlying numerous physical phenomena, including the electromagnetic response in resonators, giving…
IDToolkit: A Toolkit for Benchmarking and Developing Inverse Design Algorithms in Nanophotonics
Jia-Qi Yang, Yucheng Xu, Jia-Lei Shen +3
Aiding humans with scientific designs is one of the most exciting of artificial intelligence (AI) and machine learning (ML), due to their potential for the discovery of new drugs,…
