Abstract
Solar flares are enormous explosions on the surface of the sun and they release energy of the order of billion megatons of TNThis energy is in the form of electromagnetic radiations such as alpha, gamma, and ultraviolet rays. When exposed to high doses of radiation like 2-15 kilorad (Si), silicon integrated circuits in satellite communication systems fail to operate properly, thus affecting the performance of communication systems. Therefore, the major issue that needs to be addressed is the protection of integrated circuits and their survivability when they are exposed to various space environmental hazards including high doses of electrons, protons, solar flares and other cosmic radiations. In this paper, we present a survey of novel approaches whose effectiveness in protecting communication systems in space against solar flares has been demonstrated. In particular, we explore high Z materials used to form a radiation shielding that acts as a grit-blasted screen and low Z carbon nanotechnology used to protect against protons. We also make observations regarding a 3D layered coating for improved shielding, the use of commercially available substances, and additional ionizing radiation resistance to virtually sensitive electronic devices.
