TL;DR: In this paper, a numerical approach is presented to predict and extrapolate the behavior of multishock shields in the velocity range between 8 and 15 km/s, after perforation of the shields and the generation of damage in the backwall.

TL;DR: In this article, the authors have modeled wire mesh screens of square shape made up of different conductors for optimum shielding performance, and several investigations were carried out for the estimation of shielding effectiveness of the considered wire mesh screen in different frequency ranges and conductive materials.
Abstract: Electromagnetic shielding for microelectronic circuits requires electromagnetic shields of light weight and low volume. The electromagnetic shields using single [1] or multi layer [2] conductors yield optimum performance but are not suitable when the size of the electronic gadget is extremely small. Wire mesh screens [4] are the best alternative electromagnetic shields for such microelectronic circuits due to their light weight and low volume. In this paper, wire mesh screens [7] of square shape made up of different conductors are modeled mathematically, for optimum shielding performance. Several investigations were carried out for the estimation of shielding effectiveness of the considered wire mesh screen in different frequency ranges and conductive materials. The analysis presented in this paper for the determination of shielding effectiveness [1, 3] is frequency sensitive and the dimension of the mesh size is assumed extremely small compared to operating wavelength. The results presented in this paper are very much useful in the design of electromagnetic shields using square wire mesh screen for microelectronic circuits.

TL;DR: In this article, a multi-shock panel comprising four equally-spaced 3D printed bumper layers, a two-walls panel with outer bumper layers sandwiching a corrugated core, and a hybrid panel with three equally spaced bumpers and a fourth corrugation bumper sandwiched between two of them were evaluated with respect to their resistance to hypervelocity impacts of mm-size debris expectable in the LEO environment.
