  3. 2. 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).

    Sammanfattning : Many mechanical properties of surface micromachined devices, such as strength and elastic properties, depend on the manufacturing process and are therefore unique to the device. In order to achieve higher precision, it is essential that correct mechanical characteristics are used in the work of designing devices. LÄS MER

  7. 5. Additive Manufacturing and Integration of 3D MEMS using Ultrafast Lasers and Magnetic Assembly

    Författare :Simone Pagliano; Frank Niklaus; Göran Stemme; Gijs Krijnen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; additive manufacturing; 3D printing; 3D micromachining; two-photon polymerization; MEMS; polyimide; ultrafast laser; laser micromachining; vertical integration; magnetic assembly; stochastic assembly; diminutive chips;

    Sammanfattning : The geometry of MEMS devices is limited by the technologies used to fabricate them. Today, microsystems are manufactured with patterning technologies that allow only for 2D and 2.5D geometries. LÄS MER
