Complete with embedded wireless capabilities, high-speed circuits and high definition graphical interfaces, modern military hardware is becoming increasingly complex. Growing technological complexities are in turn making them vulnerable to radio frequency interference (RFI) threats – a kind of electronic disturbance that can be produced by a range of electronic or electromechanical devices including personal computer and computer games, medical instruments, industrial controls and many more. The radiated energy or electronic noise often affects the performance of sensitive defense equipment such as computer windows, displays on global positioning systems and military vehicles. They start responding to these disturbances randomly and erratically, subsequently leading to dangerous outcomes. RFI shielding offers a solution to this problem. It is a protective technology that helps to manage this interference and helps ensure the reliability and functionality of the components, interconnects and subsystems within this equipment.

Electronic or electrical devices directly release RFI into the environment. There can also be the conducted RFI which comes out of various electronic gadgets and penetrates the power line chords in the vicinity. This in turn interferes with the performance of other devices on the same network. This penetration can be controlled by placing a shield right at the enclosure of the equipment. A power line filter is placed to suppress the radiation leaving the unit. This helps reduce RFI to moderate levels. Different types of shielding materials are used to provide military compliant shielding performance. These materials must be lightweight, yet sturdy, capable of withstanding extreme environmental conditions, and optically transparent.
Different RFI Materials in Use
RFI shielding solutions come in many shapes and sizes, and range from simple metal boxes to conductive foams and metal meshes. When it comes to protecting displays and touch screens from electromagnetic radiation, transparent conductive films are becoming the first choice of the military around the globe. Indium Tin Oxide (ITO) is one of the substances that are widely used to manufacture such conductive films.
Some advanced composite materials are also growing in popularity due to their lightweight, stability and resistance to chemical reaction-induced temperature changes. These high-performing materials are being increasingly used to meet aerospace shielding requirements.
