Ultrathin carpet cloak enabled by infinitely anisotropic medium
Mohammad Hosein Fakheri, Ali Abdolali
Thanks to the pioneering studies conducted on the fields of transformation optics (TO) and metasurfaces, many unprecedented devices such as invisibility cloaks have been recently r…
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…
Broadband Tunable Terahertz Polarization Converter based on Graphene-shaped Metasurfaces
Behnaz Bakhtiari, Homayoon Oraizi, Ali Abdolali
In this paper, a broadband tunable polarization converter based on graphene metasurfaces is proposed. This polarization converter works in the terahertz (THz) frequency region, usi…
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…
Time-modulated Measurements: Material Characterization Based on Scalar Reflection Data
Sepideh Ghasemi, Hamid Rajabalipanah, Majid Tayarani +2
This paper explores the time-modulated waveguide setups for unique and accurate permittivity and permeability extraction of lossy dispersive samples with phase-less measurements. W…
