Direct and High-Throughput Fabrication of Mie-Resonant Metasurfaces via Single-Pulse Laser Interference
Jonas Berzinš, Simonas Indrišiūnas, Koen van Erve +8
High-index dielectric metasurfaces featuring Mie-type electric and magnetic resonances have been of a great interest in a variety of applications such as imaging, sensing, photovol…
Ultra-narrowband polarization insensitive transmission filter using a coupled dielectric metal metasurface
Arvind Nagarajan, Koen van Erve, Giampiero Gerini
A coupled dielectric-metal metasurface (CDMM) consisting of amorphous silicon (a-) rings and subwavelength holes in layer separated by a $\textit{SiO}_{2…
Reflection confocal nanoscopy using a super-oscillatory lens
Arvind Nagarajan, L. Pjotr Stoevelaar, Fabrizio Silvestri +4
A Superoscillatory lens (SOL) is known to produce a sub-diffraction hotspot which is useful for high-resolution imaging. However, high-energy rings called sidelobes coexist with th…
A Broadband Superabsorber at Optical Frequencies: Design and Demonstration
Arvind Nagarajan, Kumar Vivek, Manav Shah +2
Metasurface based super absorbers exhibit near unity absorbance. While the absorption peak can be tuned by the geometry/size of the sub-wavelength resonator, broadband absorption c…
Metasurfaces for suppressing reflection over broadband
Anuradha Patra, Ajith P. Ravishankar, Arvind Nagarajan +1
Surfaces patterned with arrays of quasi-periodic air holes having conical depth profile have been studied for their effectiveness in suppressing air-substrate reflection in the wav…
Single and multiband THz Metamaterial Polarizers
Bagvanth Reddy Sangala, Arvind Nagarajan, Prathmesh Deshmukh +4
We report single and multiband linear polarizers for terahertz (THz) frequencies using cut-wire metamaterials (MM). The MMs are designed by finite element method, fabricated by ele…
