Statistical Analysis of Scattering Invariant Mode Wave Propagation Validated by Measurements

This paper investigates microwave propagation using Scattering Invariant Modes, validated through both experimental measurements and numerical simulations. The numerical model, based on finite metallic cylinder rods, is verified against measured data. A statistical analysis of the simulated results is conducted by varying the geometric parameters, including the radius and coordinates of the scattering structure. The findings reveal a threshold beyond which changes in geometry do not significantly affect the Scattering Invariant Modes excitation, demonstrating consistent low-loss propagation despite structural variations. This highlights the robustness of SIMs in dynamically changing environments.
