To address the problem that the black coating for spacecraft optical stealth easily falls off. this study constructs a light-absorbing spacecraft surface based on a micro/nanostructure through imitating a natural light-trapping structure. In this paper. we first analyze the optical properties of a basic stealth structure with the finite difference time domain (FDTD) method and establi... https://pyrodresoners.shop/product-category/vrx-and-goggle-modules/
