  1. 1. Micromachined Gap Waveguide Devices

    Författare :Sofia Rahiminejad; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEMS; Gap waveguides; RF; High frequency; GHz; Waveguide;

    Sammanfattning : Gap waveguide technology is a new technology that is well suited for millimeter and submillimeter applications. Compared to conventional rectangular waveguides, this technology does not need any solid conductive walls to confine the wave by utilizing metamaterial surfaces such as "bed of nails" that creates an artificial magnetic conductive surface (AMC).
