    摘要: The present disclosure relates to a metasurface arrangement including a first metasurface and a second metasurface which run mutually parallel and face each other. Each metasurface includes a corresponding periodic or quasi-periodic structure formed in a respective pattern. The first metasurface is formed in a dielectric material structure and the second metasurface is formed in either a dielectric material structure or in an electrically conducting structure. The periodic or quasi-periodic structure on the first metasurface is configured to yield a first response to an incident electromagnetic wave between the two metasurfaces, and the periodic or quasi-periodic structure on the second metasurface is configured to yield a second response to the incident electromagnetic wave between the two metasurfaces that is equivalent to the first response, thereby rendering the two metasurfaces mutually electromagnetically symmetric.

    摘要: The embodiments herein relate to a first waveguide comprising a first flange (103a) surrounding an end opening (105a) of the first waveguide (101a). The first flange (103a) comprises at least two holes (110) which are periodically distributed around the end opening (105a). The first waveguide (101a) is arranged to be connected to a second waveguide (101b) by connecting the first flange (103a) to a second flange (103b) of the second waveguide (101b) such that the end opening (105a) of the first waveguide (101a) faces an end opening (105b) of the second waveguide (101b) and such that the holes (110) in the first flange (103a) are at least partly glide symmetrically positioned with respect to holes (110) which are periodically distributed around the end opening (105b) of the second flange (103b).
