  1. 11. On conceptual modelling of mode switching systems

    Författare :Ulf Söderman; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis deals with fundamental issues underlying the systematic construction of behaviour models of physical systems, especially man made engineering systems. These issues are important for the design and development of effective computer aided modelling systems providing high-level support for the difficult task of modelling. LÄS MER

  5. 14. Symmetrical FET Modeling

    Författare :Ankur Prasad; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; switch model; symmetrical model; nonlinear model; small-signal model; GaAs; Microwave FET; GaN;

    Sammanfattning : This thesis deals with empirical modeling of symmetrical Field-Effect Transistors (FETs). It covers three distinct topics within the areas of modeling and parameter extraction of microwave FETs.First, the symmetry of FET devices is addressed. Such devices are often used in transceivers as a building block for switches. LÄS MER

  7. 15. Dynamic and Static Diffractive Optics - some Examples

    Författare :Björn Löfving; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; subwavelength grating; spatial light modulator; phase retrieval; diffractive optics; ferroelectric liquid crystal; analog-to-digital conversion; optical switch; feedback generated hologram;

    Sammanfattning : Diffractive optics is a modern branch of optics, that exploits microstructures to manipulate the propagation of light. Fast computers and the progress in manufacturing technique of microelectronics have made possible a rapid development of diffractive optics during the past 10 years. LÄS MER
