  • Patent number: 10431862
    Abstract: An apparatus is provided for causing a phase-shift in reflected signals that are a reflection of surface-traveling wave signals of a select signal frequency. The apparatus comprises a conductive strip having a plurality of slots therein alternatingly arranged orthogonal to each other, each slot having an effective length that is a fraction between 9/16 and ? of the wavelength associated with the select signal frequency, and a plurality of conductive enclosures respectively disposed under each of the plurality of slots. Each of the conductive enclosure have a width and length sufficient to enclose a respective corresponding slot, and a depth that is a fraction of between ? and ? of the wavelength associated with the select signal frequency when transmitted in the dielectric material.
    Type: Grant
    Filed: October 10, 2018
    Date of Patent: October 1, 2019
    Assignee: THE BOEING COMPANY
