Abstract :
2D multiple scattering modeling of GHz waves propagating from a source within a loaded aircraft cavity is considered, with trivial computational effort. The periodic array of seats within the aircraft cavity can be readily modeled by longitudinal phase screens in the z-direction, while physical variations within a row can be modeled by a random refractive index with appropriate statistics. The effects of the scattering parameter /spl Gamma/ on the field intensity has been exhibited with strong scattering, leading to sharp, numerous and strong /spl delta/-function spikes as opposed to the low scattering limit in which the field intensities remain diffuse, broad and not as strong. This can have implications to the occurrence of hot spots within an aircraft cavity due to an electromagnetic source (e.g., PED) within the cavity.
