A single metagrating metastructure for wave-based parallel analog computing
Hamid Rajabalipanah, Ali Momeni, Mahdi Rahmanzadeh +2
Wave-based signal processing has witnessed a significant expansion of interest in a variety of science and engineering disciplines, as it provides new opportunities for achieving h…
Reciprocal Metasurfaces for On-axis Reflective Optical Computing
Ali Momeni, Hamid Rajabalipanah, Mahdi Rahmanzadeh +4
Analog computing has emerged as a promising candidate for real-time and parallel continuous data processing. This paper presents a reciprocal way for realizing asymmetric optical t…
Graphene-assisted metagrating: from coherent to angular-asymmetric control of absorption and reflection
Ensiye Ghorbanpour, Sahar Behroozinia, Ali Abdolali
In this paper, we exploit the metagrating paradigm to achieve coherent control of absorption and reflection in a two-port device. Employing graphene ribbon as a tunable element all…
Multifocal Terahertz Lens with Adjustable Focal Points
Ali Abdolali, Roya Kargar, Kasra Rouhi
The conventional lens's tunability drawback always restricts their application compared to the metasurface lens (metalens). On the other side, reconfigurable metalenses offer the b…
Scattering-free routing of surface plasmon polariton waves with optical null medium
Ali Abdolali, Atefeh Ashrafian, Hooman Barati Sedeh +1
Recently, guiding electromagnetic surface waves without sacrificing scattering losses through paths that have arbitrary shape bumps has gained a lot of interest due to its wealth o…
Parallel Optical Computing Based on MIMO Metasurface Processors with Asymmetric Optical Response
Amirhossein Babaee, Ali Momeni, Ali Abdolali +1
We present a polarization-insensitive metasurface processor to perform spatial asymmetric filtering of an incident optical beam, thereby allowing for real-time parallel optical pro…
