Surface Susceptibilities as Compact Full-Wave Simulation Models of Fully-Reflective Volumetric Metasurfaces
Ville Tiukuvaara, Tom. J. Smy, Karim Achouri +1
While metasurfaces (MSs) are constructed from deeply-subwavelength unit cells, they are generally electrically large and full-wave simulations of the complete structure are computa…
Extension of Lorentz Reciprocity and Poynting Theorems for Spatially Dispersive Media with Quadrupolar Responses
Karim Achouri, Olivier J. F. Martin
We provide a self-consistent extension of the Lorentz reciprocity theorem and the Poynting theorem for media possessing electric and magnetic dipolar and quadrupolar responses rela…
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…
Multipolar Origin of the Unexpected Transverse Force Resulting from Two-Wave Interference
Karim Achouri, Andrei Kiselev, Olivier J. F. Martin
We propose a theoretical study on the electromagnetic forces resulting from the superposition of a TE and TM plane waves interacting with a sphere. Specifically, we first show that…
Metasurface Modeling by a Thin Slab
Mojtaba Dehmollaian, Yousef Vahabzadeh, Karim Achouri +1
We investigate the possibility to model a metasurface, defined as a zero-thickness sheet of surface polarization currents, by a thin slab, characterized by a subwavelength thicknes…
Generalized Optical Signal Processing Based on Multi-Operator Metasurfaces Synthesized by Susceptibility Tensors
Ali Momeni, Hamid Rajabalipanah, Ali Abdolali +1
This paper theoretically proposes a multichannel functional metasurface computer characterized by Generalized Sheet Transition Conditions (GSTCs) and surface susceptibility tensors…
