Scattering Invariant Mode Wave Propagation in 3D Structure

This study examines low-loss microwave propagation in random media represented by 3D agroforest models. Low-loss propagation is achieved by creating scattering invariant mode (SIM) using antenna-beam forming, which is less affected by the statistical variation of the media than the regular beams used in radio wave communication techniques. The SIMs are calculated by the 3D numerical analysis of the forest. A hybrid method based on numerical calculations and the Foldy-Lax approximation is used to obtain fast results in the numerical analysis of the computationally large 3D problem. This approach makes it possible to create numerous results for building statistics for sensitivity analysis. The robustness of the Scattering Invariant Modes is examined by varying the geometry of the vegetation model.
