    Abstract: 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.

    Abstract: Some techniques and apparatuses described herein provide radio frequency (RF) beamforming using a cylindrical lens and interleaved receive and transmit antenna arrays. In one example, an apparatus for wireless communication may include a cylindrical lens having a first surface and a curved second surface opposite to the first surface. In some cases, the cylindrical lens may include a power direction corresponding to a curvature of the curved second surface and a non-power direction that is orthogonal to the power direction. In some aspects, the apparatus can include at least one receive antenna array disposed proximate to the first surface of the cylindrical lens that has a plurality of receive antenna array elements. In some examples, the apparatus can include at least one transmit antenna array disposed proximate to the first surface of the cylindrical lens that has a plurality of transmit antenna array elements.

    Abstract: Optical axis as central axis is defined as z-axis, and axes perpendicular to z-axis are defined as x- and y-axis. Metallic flat plates are formed parallel to x-z plane to overlap each other and be separated by a given distance. Multiple flat plates except the top flat plate and bottom flat plate are each provided with multiple through holes. Central flat plates are each provided with through holes of a first radius. Intermediate flat plates arranged between central flat plate and top flat plate and between central flat plate and bottom flat plate are each provided with through holes of a second radius smaller than first radius. Second radius of through holes formed in an intermediate flat plate arranged in a position farther from central flat plate is smaller than second size of through holes formed in an intermediate flat plate arranged in a position closer to central flat plate.

    Abstract: A metamaterial waveguide structure is disclosed. In some approaches the metamaterial waveguide structure is compressed along an optical axis using transformation optics techniques. An example is a Rotman lens that is compressed by 27 percent along the optical axis while maintaining the beam steering range, gain and side lobe amplitudes over a broad frequency range. In some approaches the metamaterial waveguide structure includes a plurality of complementary metamaterial elements patterned on a conducting surface of the waveguide.

    Abstract: A waveguide is disclosed that shifts the phase of the signal passing through it. In one embodiment, the waveguide has an impedance structure on its walls that resonates at a frequency lower than the frequency of the signal passing through the waveguide. This causes the structure to present a capacitive impedance to the signal, increasing its propagation constant and shifting its phase. Another embodiment of the new waveguide has impedance structures on its wall that are voltage controlled to change the frequency at which the impedance structures resonate. The range of frequencies at which the structure can resonate is below the frequency of the signal passing through the waveguide. This allows the waveguide cause a adjust the shift in the phase of its signal. An amplifier array can be included in the waveguides to amplify the signal. A module can be constructed of the new waveguides and placed in the path of a millimeter beam. A portion of the beam passes through the waveguides and the beam can be shifted or steered depending on the phase shift through each waveguide.
