2 Jan 2023 | | Abstract: | Considering the rapid progress of theory, design, fabrication and
applications, metasurface (MTS) has become a new research frontier in
microwave, terahertz and optical bands. Reconfigurable metasurface (R-MTS) can
dynamically modulate electromagnetic (EM) wave with unparalleled flexibility,
which leads to great research tide in recent years. Numerous R-MTSs with
powerful capabilities and various functions are presented explosively. In light
of the five dimensions of EM wave, this review proposes a unified model to
describe the interactions among R-MTS, EM wave and EM information, and suggests
information bit allocation strategy to categorize different types of R-MTSs
systematically. As recent advances of R-MTS, 1-bit and 2-bit elements
manipulating different wave dimensions are reviewed respectively in detail.
Finally, this review discusses the future research trends of R-MTS. Hopefully,
R-MTSs with diverse dimensions and functions can propel the next generation of
communication, detection, sensing, imaging and computing applications. | | Source: | arXiv, 2301.00593 | | Services: | Forum | Review | PDF | Favorites | |
