  1. 21. Tunable Nanomaterials and their Applications for Terahertz Devices : Carbon Nanotubes and Silver Nanowires

    Författare :Serguei Smirnov; Dmitri Lioubtchenko; Joachim Oberhammer; Hartmut Roskos; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The interest in terahertz (THz) technologies is growing in academia and industry. The design of electronic components at THz frequencies is relevant to application areas such as telecommunication, radar, material spectroscopy, and medical imaging and diagnosis. LÄS MER

  3. 22. Ultra-Wideband Low-Noise Amplifier andSix-Port Transceiver for High Speed DataTransmission

    Författare :Adriana Serban; Shaofang Gong; Ke Wu; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Today’s data rates in wired networks can reach 100 Gbit/s using optical fiber while data rates in wireless networks are much lower - tens of Mbit/s for 3G mobile communication and 480 Mbit/s for ultra-wideband (UWB) short range wireless communications. This difference in data rates can mainly be explained by the limited allowed frequency spectrum, the nature of the radio signal and the high requirements imposed on all hardware designed for high speed and wideband wireless communications.

  4. 23. On the Phase Behaviour of Soft Matter: Understanding Complex Interactions via Quantitative Imaging

    Författare :Maxime Bergman; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Microgels; Lysozyme; eye lens proteins; confocal microscopy; interaction potential; phase behaviour; simulations;

    Sammanfattning : The effect of microscopic colloid interactions on the resultant macroscopic phase behaviour is a frequently studied topic in soft matter resarch, and lies at the heart of this thesis. Key structural and dynamic properties of colloidal model systems across liquid-solid transitions are tracked using optical imaging techniques. LÄS MER
