Optically Transparent EMI Shielding for Defense and Aerospace Applications

Modern electronic devices and computing equipment are often integrated with wireless capabilities which utilize multi-bands for high speed communication, as well as high speed circuits and high definition graphical displays that operate at a wide range of frequencies. As such, hardware systems are becoming increasingly complex, resulting in products that are highly sensitive to electromagnetic interference (EMI). The vulnerability to EMI is further heightened when multiple components are packed close together within the device due to space, size and weight constraints. As such, traditional shielding methods that employ materials like thick metal Faraday cages are not always practical due to their heavy weight and bulkiness. Despite its complexity, managing this interference and increasing the resilience of components, interconnects and subsystems within the device is crucial to ensuring reliability and functionality.
