    Abstract : High Voltage (HV) rotating machines are widely used in power generation and heavy industry companies. Silicon Carbide (SiC) material is used in the stress grading structure of HV electric machines because of its non-linear characteristic. READ MORE

  6. 5. Study of different methodologies to determine relative dielectric constant of given substrate using fabrication, modelling and measurement strategies

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Anders Lundberg; [2021]
    Keywords : Relative dielectric constant; relative permittivity; PCB substrate material;

    Abstract : In this thesis, different methods for measuring the relative dielectric constant is investigated using simulations and experimental approaches. The first method is known as the S-parameter inversion method. In this method formulae is used to calculate the characteristic impedance of the microstrip line from measured S-parameters. READ MORE
