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…

Complex Eigenmodes and Eigenfrequencies in Electromagnetics
João G. Nizer Rahmeier, Ville Tiukuvaara, Shulabh Gupta
A first comprehensive treatment on complex eigenmodes is presented for general lossy traveling-wave electromagnetic structures where the per unit length propagation phase shift ($β…
