摘要:

无线传播信道的设计和优化将是未来通信技术的关键要素之一。超表面可以为无源和可调谐反射装置提供宽范围的功能,克服常用的常规相位梯度反射阵列和超表面的基本限制。在本文中,我们开发了一种有效的方法,设计和实现的超表面与高效的异常反射器功能。开发的数值方法提供了准确,快速,简单的元表面设计,考虑到非局部近场阵列元件之间的相互作用。设计方法通过毫米波段高效反常反射器的制造和实验测试得到了验证。

英文摘要:

Engineering and optimization of wireless propagation channels will be one of the key elements of future communication technologies. Metasurfaces may offer a wide spectrum of functionalities for passive and tunable reflecting devices, overcoming fundamental limits of commonly used conventional phase-gradient reflectarrays and metasurfaces. In this paper, we develop an efficient way for the design and implementation of metasurfaces with high-efficiency anomalous reflector functionalities. The developed numerical method provides accurate, fast, and simple metasurface designs, taking into account non-local near-field interactions between array elements. The design method is validated by manufacturing and experimental testing of highly efficient anomalous reflectors for the millimetre-wave band.
