A shaped power pattern synthesis with reduction of dynamic range ratio (DRR) is presented in this paper. Controlling the DRR of the excitations for the shaped power pattern synthesis is very useful since it can reduce the output power loss and also simplifies the complexity of the feeding network design. The synthesis of shaped pattern is typically a nonconvex optimization problem. To solve this problem...
Polyimide is a familiar kind of organic material for spacecraft. The deep charge of the spacecraft dielectric in the space radiation environment will eventually lead to multi-spectral impulsive discharge. The key factor that affects the dielectric charge is the conductivity of materials. The ideal situation should be that when lower charged, the dielectric presents a property of high insulation with...
