A frequency dependent model of sheet resistance of trans- parent conductive mesh coatings is proposed based on transmission line theory and vilifled by experiments. And the efiect on shielding efiectiveness of frequency dependent sheet resistance is analyzed. Sim- ulation results of shielding efiectiveness are compared with the exper- imental data of a mesh-coated window sample with equivalent param- eters fabricated and measured by Exotic Electro-Optics. The agree- ment between experiment and simulated proves the validity of the pro- posed sheet resistance model. So it can be therefore concluded that the frequency dependent model can be used to reasonably evaluate sheet resistance and shielding efiectiveness of transparent conductive mesh coated windows.
