“…Studies on the applicability of these to FSOC satellites and their qualification for the space environment should be investigated in the coming years. 165 Due to their versatility and low mass, diffractive optical elements have been proposed for FSOC for signal multiplexing, 166,167 multibeam transmitter design, 168 system size reduction, 169,170 and beam spot size reduction. 171 Although athermalization of diffractive elements has been investigated previously, 172,173 a better understanding of the opto-thermo-mechanical phenomena in this type of component is required to be used in FSOC satellite terminals.…”

Growing interest in free-space optical communication, due to the high bandwidth and security provided by these links, has generated the necessity of designing high-performance satellite terminals. In order to develop these terminals, the optothermo-mechanical phenomena that appear in the space environment and their effect on optical communication links have to be understood in detail. A review of the opto-thermo-mechanical phenomena occurring in spaceborne terminals is presented, describing the relevance of each of them. The methods found to compute the impact on the communication performance due to opto-thermo-mechanical phenomena are collected by building the bridge between the optical and communication performance parameters. Finally, techniques available to mitigate the detrimental effects of these phenomena are classified, and the relevant research challenges are identified.

“…With the help of a nonuniform distribution of shunting circuits, Liu et al 9 improved the vibration suppression effect of a finite hybrid piezoelectric phononic crystal beam. Yoon et al 10,11 presented a pendulum‐type elastic metamaterial for absorbing the vibration of a tether system, but it has a high‐frequency range of the band gap. In conclusion, elastic metamaterials are widely used for vibration suppression.…”

This study proposes a spider-web elastic metamaterial to suppress vibrations in space slender structures, such as flexible space tethers. The metamaterial consists of unit cells that are periodically distributed on the space tether to obtain band gaps. The finite element model of the unit cell is established by employing the absolute nodal coordinate formulation (ANCF) due to the large deformation of the structure. The eigenfrequencies and corresponding vibration modes of the unit cell are obtained by ANCF. Moreover, the band gap of the unit cell is calculated based on the phonon crystal theory. The relationship between the vibration modes and the band gaps is analyzed. Finally, an experiment is conducted to verify the vibration transmission characteristics of finite period cells. The results show the effectiveness of the spider-web elastic metamaterial for vibration suppression of a flexible tether. This study provides insights into the use of elastic metamaterials for vibration isolation in space tether systems.

“…The first locally resonant EMM consisted of spherical masses set into the centre of rubber cubes [22], and since then designs have included: cantilever resonators, with [23,24] or without [25] mass loading; massloaded helical springs [26]; and pendula [27]. More complicated cutout geometries based on cantilever motion have also been used [28], and zig-zag cantilevers have been used to significantly lower the resonance frequencies by folding the beam on itself [29], similar to the folded Helmholtz absorbers used in some acoustic metamaterials [30].…”
