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…
Analytical Design for Full-space Spatial Power Dividers Using Metagratings
Hamid Rajabalipanah, Ali Abdolali
We present a rigorous theoretical framework for designing full-space spatial power dividers using metagratings. In our study, the current restrictions of spatial power dividing pla…
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…
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…
Electromechanically Programmable Space-Time-Coding Digital Acoustic Metasurfaces
Hamid Rajabalipanah, Mohammad Hosein Fakheri, Ali Abdolali
Over the last couple of years, the digital coding acoustic metasurfaces have been developed rapidly as a highly active research area for their unique and flexible manipulation of a…
How Do Space-Time Digital Metasurfaces Serve to Perform Analog Signal Processing?
Hamid Rajabalipanah, Ali Abdolali, Shahid Iqbal +2
In the quest to realize analog signal processing using sub-wavelength metasurfaces, in this paper, we demonstrate the first experimental demonstration of programmable time-modulate…
