Dielectric Materials
Dielectric materials are insulating materials that can store electrical energy in an electric field. In space and astronautical engineering, dielectric materials are used in various applications such as capacitors, antennas, and solar cells. They are also used in spacecraft to protect electronic components from radiation and to provide thermal insulation. Dielectric materials have a high dielectric constant, which is a measure of their ability to store electrical energy. They are also characterized by their dielectric strength, which is the maximum electric field that they can withstand before breaking down. Dielectric materials can be natural, such as mica and quartz, or synthetic, such as ceramics and polymers. The choice of dielectric material depends on the specific application and the required electrical and mechanical properties.
