A Fast Macromodeling Approach to Efficiently Simulate Inhomogeneous Electromagnetic Surfaces
Utkarsh R. Patel, Piero Triverio, Sean V. Hum
The full-wave simulation of complex electromagnetic surfaces such as reflectarrays and metasurfaces is a challenging problem. In this paper, we present a macromodeling approach to…
