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…

Design of Rectangular Waveguide-fed Metasurfaces for Near-Field Shaping using a Coupled Dipole Model
Insang Yoo, Dong Hwan Min, Thomas Fromenteze +1
We present the design of rectangular waveguide-excited metasurfaces for near-field shaping using a coupled dipole framework. Waveguide-fed metasurfaces are array-like radiating sys…

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 (…
