In order to meet the requirements of the electro-magnetic shielding efficiency and high transmittance of some finite large optical Windows such as optoelectronics, weapons and medical treatment, the electromagnetic shielding of finite large optical Windows is studied in this paper. Firstly, a method based on CST simulation software is proposed to calculate the electromagnetic shielding efficiency of metal mesh with finite large Windows. The difference of electromagnetic shielding effi-ciency of optical Windows with different sizes is studied. It is found that in the range of 1-18GHz, there is a peak screen effect of finite large optical Windows, and the peak frequency is negatively correlated with the window size. In addition, the electro-magnetic shielding efficiency of triangular, square and circular optical Windows with different shapes is studied. In the range of 5-18GHz, the shielding efficiency of the three optical Windows with different shapes is very close, but in the range of low frequency band 1-5GHz, the electromagnetic shielding efficiency of the circular window is the highest. At 1 GHz, it is 7.6dB and 15.2dB higher than the square and triangle light Windows, re-spectively.
