The Impedance of Optically Transparent Thin Mesh Wire RF Devices

Planar optically transparent RF devices create the opportunities to deploy communication systems in more diverse locations due to their transparency and aesthetics. Conductive thin mesh wires are preferred among other transparent conductors due to their low surface resistivity high optical transparency, and low manufacturing cost. This work presents the impedance analysis of thin mesh wire devices when excited by tangential wave. It calculates inductance (L), capacitance (C) of thin mesh wire devices, and analyzes their impacts on transparent RF devices performance. The transmission line theory (TL) is used in the analysis, Ansoft HFSS software is used to simulate, and validate the analytically computed results.
