Hi Nicolas,
This is a possible solution for simulating RIS in your urban ray tracing model with comm.RayTracingChannel:
Simulating RIS with Ray Tracing:
- Model the RIS as scatterers: Instead of a single block, represent the RIS as multiple scattering elements within your simulation. Each element would have adjustable properties to reflect the reconfigurable nature of RIS.
- Modify Ray Paths: When a ray interacts with an RIS element, its path should be adjusted based on the element's configuration at that moment. This would account for the signal reflecting or refracting in specific directions.
- Optimize RIS Configuration: The ultimate goal might be to find the optimal configuration for the RIS elements to achieve the desired signal behavior at your target location. This would likely involve some optimization techniques.
MATLAB Toolbox Options:
- Phased Array System Toolbox: This toolbox deals with phased antenna systems, which share some similarities with RIS concepts. It might provide helpful insights for modeling the RIS behavior.
- Physical Modeling Toolbox : If your RIS involves metamaterials, this toolbox might be useful for creating more physically accurate models of the scattering elements.
