  2. 2. Quantum Correlations and Temperature Fluctuations in Nanoscale Systems

    University dissertation from Lund University, Faculty of Science

    Author : Fredrik Brange; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum transport; electronic entanglement; nanoscale thermodynamics; quantum calorimetry; Fysicumarkivet A:2019:Brange;

    Abstract : This thesis addresses two different topics related to the physics of nanoscale systems. The first topic concerns quantum correlations and entanglement between electrons in solid-state systems, with a focus on how to generate electronic orbital entanglement on a sub-decoherence time scale and how to achieve experimentally more feasible entanglement detection schemes.

  3. 3. Gap Waveguide for High Frequency Microwave Application- Validation of Concept, Filter Design & Packaging Aspects

    University dissertation from Lund University, Faculty of Science

    Author : Ashraf Uz Zaman; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parallel plate stopband; PMC packaging; gap waveguide; fractional bandwidth; Quasi-TEM mode; PMC surface; narrowband filter; high Q resonators;

    Abstract : The overall goal of this thesis is to validate the low loss performance of recently evolved gap waveguide technology and to use this low loss technology for designing critical passive microwave component such as narrow band filter. Also, the exploitation of gap waveguide concept as a packaging solution for densely packed RF circuitry has been presented in this thesis. READ MORE

  4. 4. Gap Waveguide: Low Loss Microwave Passive Components and MMIC Packaging Technique for High Frequency Applications

    University dissertation from Lund University, Faculty of Science

    Author : Ashraf Uz Zaman; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Quasi TEM; Slot Array; PMC; Gap waveguide; Narrow-band Filter;

    Abstract : The heavy congestion at the existing radio frequency spectrum allocated for the today’s wireless communications motivates and accelerates the research work at mmWave bands or even higher frequency range where more spectrum space is available for massive data rate delivery. The inclination of modern wireless system research and development is towards small size, reliable, high-performance and high-yield microwave multifunctional products. READ MORE
