The 2024 Active Metamaterials Roadmap
Simon A. Pope, Diane J. Roth, Aakash Bansal +27
Active metamaterials are engineered structures that possess novel properties that can be changed after the point of manufacture. Their novel properties arise predominantly from the…
Localised Thermal Emission from Topological Interfaces
M. Said Ergoktas, Ali Kecebas, Konstantinos Despotelis +7
The control of thermal radiation by shaping its spatial and spectral emission characteristics plays a key role in many areas of science and engineering. Conventional approaches to…
Reversible Ionic Liquid Intercalation for Electrically Controlled Thermal Radiation from Graphene Devices
Xiaoxiao Yu, Gokhan Bakan, Hengyi Guo +3
Using graphene as a tuneable optical material enables a series of optical devices such as switchable radar absorbers, variable infrared emissivity surfaces, or visible electrochrom…
Electrically controlled heat transport in multilayer graphene
Pietro Steiner, Saqeeb Adnan, Muhammed Said Ergoktas +13
The ability to control heat transport with electrical signals has been an outstanding challenge due to the lack of efficient electrothermal materials. Previous attempts have mainly…
Non-Hermitian engineering of terahertz light using exceptional points in electrically tuneable collective light-matter interactions
M. Said Ergoktas, Sina Soleymani, Nurbek Kakenov +8
The topological structure associated with the branchpoint singularity around an exceptional point (EP) provides new tools for controlling the propagation of electromagnetic waves a…
Multispectral Electro-Optical Surfaces: from Visible to Microwave
M. Said Ergoktas, Gokhan Bakan, Evgeniya Kovalska +9
Optical materials with colour-changing abilities have been explored for display devices, smart windows, or modulation of visual appearance. The efficiency of these materials, howev…
Video-speed Graphene Modulator Arrays for Terahertz Imaging Applications
Yury Malevich, M. Said Ergoktas, Gokhan Bakan +2
Electrically tuneable high mobility charges on graphene yield an efficient electro-optical platform to control and manipulate terahertz (THz) waves. Real-world applications require…
Graphene-based Soft Wearable Antennas
Isidoro Ibanez-Labiano, M. Said Ergoktas, Coskun Kocabas +3
Electronic textiles (e-textiles) are about to face tremendous environmental and resource challenges due to the complexity of sorting, the risk to supplies and metal contamination i…
Graphene-enabled adaptive infrared textiles
M. Said Ergoktas, Gokhan Bakan, Pietro Steiner +10
Interactive clothing requires sensing and display functionalities to be embedded on textiles. Despite the significant progress of electronic textiles, the integration of optoelectr…
Graphene Based Terahertz Phase Modulators
Nurbek Kakenov, M Said Ergoktas, Osman Balci +1
Electrical control of amplitude and phase of terahertz radiation (THz) is the key technological challenge for high resolution and noninvasive THz imaging. The lack of an active mat…
