Effect of lag correlations on the statistical modeling of wave propagation in a complex cavity [aircraft fuselage applications]
We have extended our earlier 2D multiple scattering formalism for plane GHz waves propagating down a loaded aircraft fuselage. The periodic array of seats/windows is modeled by longitudinal phase screens in the Z-direction, while scattering variations within a row are modeled by the random medium having various transverse lag-correlations. The effects of different lag-correlations and the strength of the scattering parameter /spl gamma/ on the existence of possible hot spots are readily seen, indicating that the computationally trivial approach of the multiscattering method could play a role a useful role in the determining of hot spots within an aircraft cavity due to electromagnetic sources (e.g., PEDs) within the cavity. The method is readily extended to examining polarization effects as well as 2D transverse structures.
