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…
On the Use of Electromagnetic Inversion for Metasurface Design
Trevor Brown, Chaitanya Narendra, Yousef Vahabzadeh +2
We show that the use of the electromagnetic inverse source framework offers great flexibility in the design of metasurfaces. In particular, this approach is advantageous for antenn…
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-…
