Abstract

An origami-based metasurface retroreflector is proposed to realize highly efficient wideband back reflection. The design integrates origami-based gradient phase arrays that are articulated at angles of

$\boldsymbol {\alpha = 25^{\circ } }$

and

$\boldsymbol {\beta = 45^{\circ } }$

and constitutes a

$20\times 18$

array of resonant units. By morphing a 2-D surface into a quasi-planar configuration, the retroreflector significantly broadens its operational bandwidth and enhances backscattering capabilities. Simulations and experimental validations collectively demonstrate that the origami retroreflector provides a notable 21-dB enhancement in radar cross section (RCS) within the angular range of

$ \boldsymbol {45^{\circ } \pm 4^{\circ } }$

. It exhibits a relative bandwidth of 18.87% under transverse electric (TE) polarization from 9.6 to 11.6 GHz and 15.81% under transverse magnetic (TM) polarization from 9.9 to 11.6 GHz. In addition, the retroreflector foldable nature allows for a substantial reduction in volume, reaching as low as 10% of its original size upon complete retraction. The proposed origami metasurface retroreflector exhibits potential applications in radar target detection, enemy identification, and maritime rescue due to its wideband RCS enhancement, lightweight structure, and foldable characteristics.

基于折纸超表面后向反射器的宽带高效后向散射增强

提出了一种基于折纸的超表面反反射器，以实现高效宽带反反射。该设计集成了以折纸为基础的梯度相阵，这些相阵以$\boldsymbol {\alpha = 25^{\circ } }$和$\boldsymbol {\beta = 45^{\circ } }$的角度铰接，构成了$20\times 18$谐振单元阵列。通过将二维表面变形为准平面结构，后向反射器显着拓宽了其工作带宽并增强了后向散射能力。仿真和实验验证共同表明，折纸后向反射器在$ \boldsymbol {45^{\circ } \pm 4^{\circ } }$角范围内的雷达截面（RCS）显著提高了21 db。其相对带宽为18.87% under transverse electric (TE) polarization from 9.6 to 11.6 GHz and 15.81% under transverse magnetic (TM) polarization from 9.9 to 11.6 GHz. In addition, the retroreflector foldable nature allows for a substantial reduction in volume, reaching as low as 10% of its original size upon complete retraction. The proposed origami metasurface retroreflector exhibits potential applications in radar target detection, enemy identification, and maritime rescue due to its wideband RCS enhancement, lightweight structure, and foldable characteristics.

期刊介绍： The IEEE Transactions on Microwave Theory and Techniques focuses on that part of engineering and theory associated with microwave/millimeter-wave components, devices, circuits, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, and industrial, activities. Microwave theory and techniques relates to electromagnetic waves usually in the frequency region between a few MHz and a THz; other spectral regions and wave types are included within the scope of the Society whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
