  2. 6. Graphene FETs in Microwave Applications

    Author : Omid Habibpour; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microwave amplifiers; S-parameters characterisation; device modelling; MMIC; device fabrication; Graphene; subharmonic resistive mixers; integrated circuits; harmonic balance analysis; microwave FETs;

    Abstract : Graphene is a one-atom-thick sheet of carbon with numerous impressive properties. It is a promising material for future high-speed nanoelectronics due to its intrinsic superior carrier mobility and very high saturation velocity. READ MORE

  4. 7. Towards Microwave Detection of Thromboses

    Author : Seyed Moein Pishnamaz; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antenna.; Thromboses; Microwave; Stroke;

    Abstract : Stroke is estimated to be the second most common cause of death with huge burdens and costs for the patient and society. Since the treatment given to a stroke patient depends on the type of stroke they have, a fast and reliable diagnosis of the stroke type is needed before any treatment can be started. READ MORE

  5. 8. Silicon Carbide Microwave Devices

    Author : Joakim Eriksson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SBD; high-power microwave devices; Silicon Carbide; diode mixer; wide band gap devices; physical simulations; resistive mixer; microwave devices; MESFET; Schottky diode;

    Abstract : This work deals with silicon carbide (SiC) microwave devices. It treats two devices; the Schottky diode and the metal semiconductor field effect transistor (MESFET). Different MESFET materials, fabrication processes, theoretical models for physical simulation, and device models are presented. READ MORE

  6. 9. Evaluation of biomedical microwave sensors : Microwave sensors as muscle quality discriminators in laboratory and pilot clinical trial settings

    Author : Viktor Mattsson; Robin Augustine; Mauricio Perez; Roger Karlsson; Ayca Özcelikkale; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microwave sensors; Sarcopenia; Muscle quality assessment; Biomedical applications; Tissue dielectric properties; Data-driven modelling; Clinical trials; EM Simulations; Phantom experiments; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Abstract : In this thesis the primary focus is on the evaluation of biomedical microwave sensor to be used in the muscle analyzer system. Lower muscle quality is one indicator that a patient can have sarcopenia. Therefore the muscle analyzer system can be a tool used in screening for sarcopenia. READ MORE

  7. 10. Resonant Microwave Sensors for Industrial Applications

    Author : Johan Nohlert; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element method; eigenvalue problems; microwave resonances; parameter estimation; process monitoring; microwave measurements; detection;

    Abstract : This thesis presents developments in the area of microwave-based sensor systems for industrial applications. The work is motivated by a need for advanced measurement techniques in industry in general, and the process industry in particular. READ MORE
