Shanghai Metal Corporation is a Aluminum Waveguide Window manufacturer and supplier.

Shielded waveguide ventilation windows are constructed from hexagonal honeycomb core material with a frame. While ensuring efficient ventilation, they also utilize the high-pass, low-resistance principle of shielded waveguides to effectively shield electromagnetic waves (EMI). Generally, the shielding principle of shielded waveguides is: L≥5D (L: waveguide length, D: maximum diameter of the waveguide cross-section). Therefore, the shielding effectiveness of a shielded waveguide ventilation window depends on the length of the waveguide (i.e., the thickness of the honeycomb core and the size of the honeycomb core aperture).
