Equivalent Circuit Modeling and Design of a Reconfigurable Loaded Dogbone Metasurface Element
Christopher T. Howard, William D. Hunt, Kenneth W. Allen
The accelerating trend of active metasurfaces -- such as those incorporating non-Foster matching, programmable control, or space-time modulation -- adds complexity to the computati…

Multimodal Effective Permittivity Model for Metasurfaces Embedded in Layered Media
Christopher T. Howard, William D. Hunt, Kenneth W. Allen
The dielectric layers surrounding a metasurface have a large impact on its frequency and angular response. The notion of effective permittivity captures this dependence by suggesti…
