Investigation of Broadband Shielding Effect in Mesh Transparent Conductor with Irregular Structure

a silver irregular micromesh transparent conductors with excellent combination of optoelectric characteristics have been obtained in this work. Broadband measurements of EMI shielding properties irregular mesh transparent conductor have been carried out. It is shown that in the high-frequency region the shielding ability reaches saturation and becomes indistinguishable for 600 nm and 1000 nm thick silver mesh transparent conductors. As expected, the key factor for mesh transparent conductor coatings is the average cell size, which turns out to be the limiting factor for shielding at high frequencies. The experimental data are in agreement with the Kantorovich model.
