“…The discussions and applications of random rough surfaces in the area of light waves include: 1. Rough surfaces can be formed on the radiators of space vehicles due to local accumulation of dust, which will change the emissivity of the radiating surface and affect the overall heat dissipation performance of the radiator [2], 2. Temperature readings need to be taken in the rapid thermal annealing conducted in nano processing.…”

This article describes the development of a suite of programs that is capable of simulating the radiation properties of a random rough surface (RRS). The fundamental approach involves the generation, by fast Fourier transform (FFT) built with rigorous finite difference time domain (FDTD), as the theoretical basis for the simulation of a bidirectional reflectance distribution function (BRDF) of the RRS. The results are compared with the measurements and modeling of existing work to verify the feasibility of customized programming. It was found that the results of this study were a better match to the measurement data than those achieved in other modeling work.

“…To minimize the effect of such dispersion on the modeling results, the method suggested by Taflove and Brodwin [20] is utilized. Here the maximum spatial grid size (Δx and Δy) is set to be one-twentieth of the wavelength λ, with the temporal grid Δt set by equation (2).…”

All spacecraft must include a thermal control system (TCS) to maintain equipment and/or crew within tolerable temperature limits during the mission. This chapter provides an overview of spacecraft thermal control systems design and development, with descriptions of the passive and active subsystems and associated components. The necessary steps in the design process are also provided, including establishing mission and system requirements, characterizing the mission environments, developing the design concept and models, and planning a test program to ensure the system functions as expected.
