  2. 1. Applications of Microwave Heating of Foods

    Author : Birgitta Wäppling-Raaholt; Birgitta Raaholt; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; modelling of microwave heating; microwave-assisted HTST processing; product quality.; heat transfer; microwave heating; microwave oven; heating uniformity; microwave cavity; tubular microwave in-flow processing;

    Abstract : AbstractMicrowave heating of foods offers rapid and flexible heating both for consumer and industrial applications, with several advantages, such as reduced processing time (due to volumetric heating and reduced coming-up times (heating time required to reach the desired target temperature), selective heating, increased process flexibility and efficient heating (volumetric heating of the food does not require heating of a surrounding medium or package). However, successful installations requireknowledge in process design. READ MORE

    Abstract : Microwave tomography for non-destructive detection of internaldielectric properties has received increasing interest during the lastdecades. Several application areas are under research, includingapplications in geoscience, biomedical applications, safety andsecurity etc. READ MORE

  5. 3. Microwave power device characterization

    Author : Kristoffer Andersson; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; statistical estimation; self-heating; Silicon Carbide; Gallium Nitride; mixer; thermal resistance; wide bandgap; microwave; error-correction; small-signalmodel;

    Abstract : The first part of the thesis covers work done on device characterizationmethods. A statistical method for estimating small-signal model parametersin FET-models was proposed. A maximum likelihood estimator wasderived and the new method was compared to a standard direct extractiontechnique. READ MORE
