Non-Metallic Transparent Enclosure Performance Improvement using Gold Nano-Layer Film

In this paper, we present a practical solution to improve the performance of non-metallic transparent enclosures (NTE) using gold Nano-layer deposition. Firstly, based on Robinson et al. method, an analytical model is introduced to approximately estimate shielding effectiveness of transparent enclosures. While Robinson et al. model cannot analyses NTE, due to its inability to take into account multi-layer panel effects and another effective analytical model has not been reported in previous works, proposed analytical model have an acceptable agreement with simulation and measurement results. In the next step, by making a tradeoff between shielding effectiveness and optical transparency, an optimum thickness of gold Nano layer is selected and deposited on the ITO glass panels by thermal evaporation technique, to improve the NTE performance. Finally, to assess the performance optimization method, results of copper, ITO Glass, and gold deposited enclosures are compared to introduce gold deposited ITO Glass enclosure provides good shielding effectiveness similar to copper one (about 20dB better than ITO Glass enclosure) as well as acceptable optical transparency in visible range, whereas metallic enclosures cannot provide any transparency.
