Semi-analytical Model of Multi-tile Rectangular Waveguide-fed Metasurfaces using Coupled Dipole Modeling Framework
Insang Yoo, Michael Boyarsky, David R. Smith
We present a semi-analytical model to analyze multi-tile metasurface antennas consisting of a set of metasurface tiles and a practical power-dividing network that excites the tiles…

Equivalent Circuit Models for Waveguide-Fed, Resonant, Metamaterial Elements
David R. Smith, Yeonghoon Noh, Insang Yoo +2
We propose an approach to extracting equivalent circuit models for waveguide-fed, resonant metamaterial elements, such as the complementary, electric inductive-capacitive element (…

Equivalence of Polarizability and Circuit Models for Waveguide-Fed Metamaterial Elements
David R. Smith, Mohsen Sazegar, Insang Yoo
A common variant of a metasurface antenna consists of an array of metamaterial elements coupled to a waveguide feed. The guided wave excites the metamaterial elements, coupling ene…
