Enhancing Transparency and EMP Shielding Based on Low-E Glass Windows Using Thin Conductive Films for Civil and Military Applications

Thin conductive coatings on glass substrates have attracted more attention for their dual purpose in thermal insulation and electromagnetic shielding. However, although many papers exist on the microwave transmission properties of coating window glass at low frequencies, there seems to be shortage in research that highlights the relationship between optical transmittance, low emission windows, and electromagnetic shielding in a larger frequency spectrum. This research demonstrates that electromagnetics shielding significantly is greater than traditional conductive windows, with attenuation levels above 80 dB over the frequency range of 0.3 GHz to 18 GHz. Comparative analysis of observed and predicted data indicates that Low-E coated glass is an excellent choice for commercial and military sites necessitating greater electromagnetic shielding, while preserving transparency and low emission performance.
