1 May 2020 | | Abstract: | We report a waveform-selective metasurface that operates at 2.4 GHz band,
i.e. one of ISM (Industrial, Scientific and Medical) bands. This structure
gives us an additional degree of freedom to control electromagnetic waves and
absorbs a particular waveform or pulse width of an incident wave at the same
frequency band, while transmitting others. This unique capability is
demonstrated using either ideal sinusoidal waves or Wi-Fi signals as a more
practical waveform in wireless communications. Especially, this study shows how
the waveform-selective metasurface interacts with realistic wireless
communication signals from the viewpoint of communication characteristics, such
as EVM (Error Vector Magnitude), BER (Bit Error Rate) and phase error. Thus,
our study paves the way for extending the concept of waveform selectivity from
a fundamental electromagnetic research field to a more realistic wireless
communication field to, for instance, mitigate electromagnetic interference
occurring at the same frequency band without significantly degrading
communication characteristics. | | Source: | arXiv, 2005.0233 | | Services: | Forum | Review | PDF | Favorites | |
