Electromagnetic Shielding with Transparent Coated Glass

Transmission of uniform plane waves at normal incidence through a multilayer transparent coated glass structure, with thin conductive layers, is investigated. Dependence of the degree of shielding obtainable on the type of construction, thickness and dielectric constant of the glass layers, and on the surface resistivity of the coating is studied from the standpoint of both analysis and design, and correlated with the resulting transparency. Dependence on frequency and, to some extent, reflection from the structure, are also investigated. Theoretical results are correlated with experimental data to show the applicability of this analysis to practical cases of more complex fields.
