  1. 1. Microwave power device characterization

    Author : Kristoffer Andersson; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

  5. 5. Migration from plastic food packaging during microwave heating

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Jonas Alin; KTH.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; migration; food packaging; microwave; degradation; food simulant; antioxidant;

    Abstract : Microwave heating of food has increased rapidly as a food processing technique. This increases the concern that chemicals could migrate from food packaging to food. The specific effect of microwave heating in contrast to conventional heating on overall and specific migration from common plastic food storage boxes was studied in this work. READ MORE
