Shielding Effectiveness of a Spacecraft Faraday Cage With Pin 1 Connections
Estimates are made of the shielding effectiveness (SE) of a satellite Faraday cage with Pin 1 connections. Degradation of the SE by space radiation and solar-thermal cycling is described. The impact of multilayer insulation on the SE is assessed.
Formula for the Shielding Effectiveness of a Rectangular Cavity With a Penetrating Cable
A formula is derived for the plane wave shielding effectiveness of a spacecraft Faraday cage with a penetrating cable. The potentially disastrous effects of space radiation, corrosion, and thermal cycling are described.
Creating the Virtual Universe
Simulation software is important to our understanding of the universe. The intrinsic multiphysics aspects are spiced with a range of temporal scales and spatial scales, both of which cover more digits than are available in the standard hardware. This, together with the intrinsic chaotic nature of many physical processes, poses quite a challenge. To meet this challenge, researchers developed the Astronomical Multipurpose Environment (AMUSE). Instead of writing a suite of multiphysics solvers from scratch, AMUSE's developers coupled existing solvers for each physical ingredient. The result is a highly inhomogeneous collection of dedicated solvers with a homogeneous protocol that scales to supercomputers.
