A QuaDRiGa-Based Simulation Platform for Reconfigurable Intelligent Surfaces

QRIS is a flexible and accurate platform that can be used to evaluate the performance of wireless systems with RISs in various scenarios with any number of RIS, transmitters (Tx), and receivers (Rx). QRIS allows using various UC radiation patterns, including realistic ones, obtained from real measurements or comprehensive simulation using CST Microwave Studio. QRIS includes UCs models that take into account polarization, radiation pattern, Radar-Cross Sections (RCS), and phase shift variations depending on the angle of incidence. QRIS is suitable for the evaluation of scenarios with multiple RIS, including multi-hop transmissions. QRIS has an accurate channel model based on QuaDRiGa. Consequently, QRIS can be used for a wide frequency range, various RIS positions, and multiple antennas on Tx and Rx for MIMO evaluation. QRIS is ready to integrate with system-level simulation platforms to study cooperation of RIS and widely used technologies such as 5G and Wi-Fi 7, and also those which are under development. The development of QRIS has already demonstrated significant results in evaluating realistic RIS scenarios.
