  • Publication number: 20190137793
    Abstract: A method for regulating the phase of a wide-band electromagnetic wave uses a meta-surface sub-wavelength structure and the meta-surface sub-wavelength structure. The sub-wavelength structure is used as a basic unit of the meta-surface, and the basic unit is arranged in an array according to a regular order determined by the predetermined phase to generate a geometrical phase distribution with the spatial continuity and the spectral achromaticity between 0 and 2?, so that the phase is controlled and modulated in a two dimensional plane. The operating bandwidth may cover the entire electromagnetic spectrum, and a variety of optical devices such as reflective focusing/imaging elements, transmission focusing/imaging elements, prisms, orbital angular momentum generator may be realized. As an extension of the phase regulation, the method may also realize other novel electromagnetic wave functions such as wideband absorption and radar cross section reduction.
