Abstract: With the plex of ic environment of space, specific
ic shielding requirements are needed for optical transparent objects including optical
windows, in the fields such as aerospace equipment, which can be epitomized by considering high
transmisitivity, strong ic shielding and low effect on imaging quality simultaneously.
Metallic mesh ic shielding technique is such an effective method that it attracts wide
attention and research. This paper introduces the existing problems and research progress of
metallic mesh ic shielding technique in ic shielding situation. First,
The paper expounds the limitations of square mesh, including mutual constraints between
ic shielding efficiency and light transmittance and concentration of high-order
