Abstract: Amethod for calculatingthe radiation properties ofwire meshes is presented, inwhichthe effects of scattering and surface characteristics are both taken into consideration, and the stratified superposition principle and a double-flux model are employed. Finally the calculated results are compared with those obtained by projective theory and Mie electromagnetic theory, and confirmed by a high temperature wind tunnel experiment. It is shown that the results by this method coincide with the experimental results well.
