Semi-analytical Model of Multi-tile Rectangular Waveguide-fed Metasurfaces using Coupled Dipole Modeling Framework

David R. Smith, Insang Yoo, Michael Boyarsky

A coupled-dipole framework paired with multi-port network analysis forms a self-consistent semi-analytical model for multi-tile waveguide-fed metasurface antennas.

Claims

C1strongest claim

The proposed semi-analytical model employs a coupled-dipole framework that accurately captures dipolar interactions among constituent elements within the metasurface tiles, along with a multi-port network analysis technique that accounts for electromagnetic interactions between the tiles and the power divider, thereby forming a self-consistent formulation.

C2weakest assumption

The metasurface tiles consist of arrays of rectangular waveguides with subwavelength metamaterial radiators etched into their top walls, each of which can be accurately modeled as polarizable dipoles (and likewise for the coupling slots).

C3one line summary

A coupled-dipole semi-analytical model for multi-tile rectangular waveguide-fed metasurfaces that forms a self-consistent formulation and is validated against full-wave simulations.
