The main theme of this thesis is the design and verification of electromagnetic
shielding for observation windows in electromagnetic isolation environment. The
shielding frequency range is 30 MHz to 960 MHz, which is the electromagnetic protection frequency range for electromagnetic protection of electronic products. The content first analyzes the shielding effect of conductive glass through electromagnetic simulation and proposes a structure that meets the requirements through a combination arrangement.
Three measurement methods are proposed: the coaxial fixture measurement method,
which measures the shielding effect at low frequencies; the free space measurement method, which measures the shielding performance in free space in a microwave
darkroom; and the simulated lightning strike measurement method, which measures the shielding effect in a high electric field.
And by selecting the surface structure with frequency, using the slot structure, data transmission can be performed at a frequency of 2.4 GHz. Three designs are proposed, namely the basic cross, the Jerusalem cross, and the swastika. A comparison of their advantages and disadvantages is analyzed, and the cross design is ultimately chosen. The unit size is 45 mm x 45 mm, and 10 mm reinforced glass is used as the substrate. This structure exhibits good shielding performance in the shielded frequency range. Finally, a summary is made of the content mentioned in the article, and future applications and measurement directions are considered.
