Computational Analysis of Metasurfaces
Yousef Vahabzadeh, Nima Chamanara, Karim Achouri +1
Metasurfaces represent one of the most vibrant fields of modern science and technology. A metasurface is a complex electromagnetic structure, that is typically deeply subwavelength…
Efficient GSTC-FDTD Simulation of Dispersive Bianisotropic Metasurface
Yousef Vahabzadeh, Nima Chamanara, Christophe Caloz
We present a simple and efficient Finite-Difference Time-Domain (FDFD) scheme for simulating dispersive (Lorentz-Debye) bianisotropic metasurfaces. This scheme replaces the convent…
Synthesis of Spherical Metasurfaces based on Susceptibility Tensor GSTCs
Xiao Jia, Yousef Vahabzadeh, Fan Yang +1
The bianisotropic susceptibility Generalized Sheet Transition Conditions (GSTCs) synthesis method is extended from planar to spherical metasurfaces. Properties specific to the non-…
Mathematical Synthesis and Analysis of Nonlinear Metasurfaces
Karim Achouri, Yousef Vahabzadeh, Christophe Caloz
We propose a discussion on the synthesis and scattering analysis of nonlinear metasurfaces. For simplicity, we investigate the case of a second-order nonlinear isotropic metasurfac…
Generalized Sheet Transition Condition FDTD Simulation of Metasurface
Yousef Vahabzadeh, Nima Chamanara, Christophe Caloz
We propose an FDTD scheme based on Generalized Sheet Transition Conditions (GSTCs) for the simulation of polychromatic, nonlinear and space-time varying metasurfaces. This scheme c…
