    Abstract : Spin-torque and spin Hall nano-oscillators are nanoscale devices (about 100 nm) capable of producing tunable broadband high-frequency microwave signals ranging from 0.1 GHz to over 65 GHz that several research groups trying to reach up to 200 - 300 GHz. READ MORE

  4. 2. Micromachined Gap Waveguide Devices

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

    Abstract : 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).
