    Accurate electromagnetic field modelling of heterogeneous dielectric geometries requires accurate complex permittivity data to be measured across the spectrum, together with magnetic parameters, where appropriate. For optimum accuracy a wide range of measurement techniques is required. Realistic measurement uncertainty estimates can provide useful inputs into the modelling process. Such measuremen...

  • Challenges in High and Low Field AC Magnetic Measurements for Material Modelling and Electrical Machine Performance Prediction

    Publication Year: 2006, Page(s):15 - 20

    This paper is limited to discussion of only a few of these aspects. It focuses on measurements on electrical steels and modelling or predicting their performance but the same issues arise in measurements on other materials for power applications such as cobalt iron alloys and soft magnetic composite cores (SMCs). For brevity, only two magnetic properties are considered, namely power loss and perme... View full abstract»

    It is important to be able to accurately evaluate the electrical properties of dielectric materials to enable the accurate design of passive microwave integrated circuit components. This paper reports on research that has been undertaken in this area at London South Bank University. Three measurement techniques are reported. The first is a novel technique for measuring dielectric materials with a ... View full abstract»

  • Dielectric ageing: materials, measurements and modelling of nano to meso scale processes

    Publication Year: 2006, Page(s):27 - 32
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (3234 KB)

    This paper considers ageing processes in polymeric dielectrics under the action of applied electric fields. Ageing can be thought of as occurring in two stages, initiation of damage and its subsequent evolution. Initially, charge carriers move through the material perturbing the local field (space charge) and inducing excited states. Such processes can result in the production of photons (electrol...

    This paper provides an outline some of the technological applications and concepts for magnetic nanostructures. The magnetization reversal processes in nanostructures are introduced and experimental studies of these processes are described along with micromagnetic simulations of the magnetization behaviour in order to understand the reversal behaviour View full abstract»

    The magnetic properties of soft magnetic materials need to be measured for conditions that represent how they are used in order to achieve more reliable devices and meet target specifications. For the purchase and sale of magnetic materials written IEC standards exist and provide the necessary framework. For AC measurements the IEC standards require waveforms to be sinusoidal as this allows compar... View full abstract»
