Part 2: Spatially Dispersive Metasurfaces -- IE-GSTC-SD Field Solver with Extended GSTCs
Tom J. Smy, João G. Nizer Rahmeier, Jordan Dugan +1
An Integral Equation (IE) based field solver to compute the scattered fields from spatially dispersive metasurfaces is proposed and numerically confirmed using various examples inv…
Part 1: Spatially Dispersive Metasurfaces: Zero Thickness Surface Susceptibilities & Extended GSTCs
João G. Nizer Rahmeier, Tom J. Smy, Jordan Dugan +1
A simple method to describe spatially dispersive metasurfaces is proposed where the angle-dependent surface susceptibilities are explicitly used to formulate the zero thickness she…
Surface Susceptibilities as Compact Full-Wave Simulation Models of Fully-Reflective Volumetric Metasurfaces
Ville Tiukuvaara, Tom. J. Smy, Karim Achouri +1
While metasurfaces (MSs) are constructed from deeply-subwavelength unit cells, they are generally electrically large and full-wave simulations of the complete structure are computa…
Metasurface Near-field Measurements with Incident Field Reconstruction using a Single Horn Antenna
Ville Tiukuvaara, Kan Wang, Tom J. Smy +1
A simple method of superimposing multiple near field scans using a single horn antenna in different configurations to characterize a planar electromagnetic metasurface is proposed…
