Attenuation characteristics of High Power Microwave (HPM) with different frequencies (L, S, C, X band) penetrating through reinforcement nets were studied by simulation tests combined with the finite-difference time-domain method in this paper. The research models reflect various kind of reinforcement nets with different diameters, different meshes, different spacings between layers, and different arrangement. The results show that shielding effectiveness of reinforcement nets against HPM exists. And shielding effectiveness is better when the mesh is smaller than half of the wave-length, or when the spacing between layers is odd number times a quarter of the wave-length, or when the reinforcement nets are arrange is stagger. The reinforcement nets with dissimilar forms can be comprehensively utilized in protective constructions for the best result. Source

According to the present properties of some new plane shielding materials and the shortages of standard test methods, two test methods of shielding effectiveness based on the shielding enclosure for plane materials were described in this paper. And these have offered perfect test facility for the performance test of shielding materials, and have supplied test channel for accurately evaluating the shielding effectiveness of materials. What's more, these would provide test platform for the couple of aperture and detection of protecting equipments. Some actual applied experiments have proved reasonability and the validity of testing methods. Source
