Adjustment of Cluster-Then-Predict Framework for Multiport Scatterer Load Prediction
Hanjun Park, Aleksandr D. Kuznetsov, Ville Viikari
Predicting interdependent load values in multiport scatterers is challenging due to high dimensionality and complex dependence between impedance and scattering ability, yet this pr…
Mutual-Coupling-Aware Optimization of a Time-Floquet RIS for Harmonic Backscatter Communications
Aleksandr D. Kuznetsov, Ville Viikari, Philipp del Hougne
This Letter studies the optimization of a wireless communications system empowered by a periodically time-modulated reconfigurable intelligent surface, coined time-Floquet RIS (TF-…
Multifrequency system model for multiport time-modulated scatterers
Aleksandr D. Kuznetsov, Jari Holopainen, Ville Viikari
Utilizing scatterers in communication engineering, such as reconfigurable intelligent surfaces (RISs) and backscatter systems, requires physically consistent models for accurate pe…
Thin Film Reconfigurable Intelligent Surface for Harmonic Beam Steering
Boxuan Xie, Aleksandr D. Kuznetsov, Lauri Mela +4
