Concept, realization, and applications of coding metasurfaces
AbstractCoding metasurfaces, characterized by processing the electromagnetic waves for specified functions through predesigned coding sequences either in space or time, can manipulate the electromagnetic waves in both space frequencies and time frequencies. They have been emerging as the revolutionary platforms for metasurface technologies in recent years. In this paper, we first introduce the general concept and operating principle of the coding metasurfaces. Then, two design strategies for realizing the coding metasurface particles, altering resonant states and switching current phase, are provided, respectively. Next, two recent reported applications that are based on space-coding metasurface for RCS reduction and time-coding metasurface for spread-spectrum wireless communication are presented, respectively. Finally, existing challenges and potential future research directions in coding metasurfaces are discussed.Keywords: Coding metasurfacespace-codingtime-codingspace-time-codingmulti-bitRCS reductionspread spectrum AcknowledgmentsThe authors would like to thank Dr. Fuheng Zhang, Dr. Yasir Saifullah, and Qingzhuo Chen for their valuable contribution to this work.Disclosure statementNo potential conflict of interest was reported by the authors.Additional informationFundingThis work was supported by the National Key Research and Development Program of China under grant number 2017YFA0100203.
期刊介绍：
Waves in Random and Complex Media (formerly Waves in Random Media ) is a broad, interdisciplinary journal that reports theoretical, applied and experimental research related to any wave phenomena.
The field of wave phenomena is all-pervading, fast-moving and exciting; more and more, researchers are looking for a journal which addresses the understanding of wave-matter interactions in increasingly complex natural and engineered media. With its foundations in the scattering and propagation community, Waves in Random and Complex Media is becoming a key forum for research in both established fields such as imaging through turbulence, as well as emerging fields such as metamaterials.
The Journal is of interest to scientists and engineers working in the field of wave propagation, scattering and imaging in random or complex media. Papers on theoretical developments, experimental results and analytical/numerical studies are considered for publication, as are deterministic problems when also linked to random or complex media. Papers are expected to report original work, and must be comprehensible and of general interest to the broad community working with wave phenomena.
