  • "Vi klimatforskare stödjer Greta och skolungdomarna"
  • 2019

  • Journal article (pop. science, debate, etc.)abstract
    • DN DEBATT 15/3. Sedan industrialiseringens början har vi använt omkring fyra femtedelar av den mängd fossilt kol som får förbrännas för att vi ska klara Parisavtalet. Vi har bara en femtedel kvar och det är bråttom att kraftigt reducera utsläppen. Det har Greta Thunberg och de strejkande ungdomarna förstått. Därför stödjer vi deras krav, skriver 270 klimatforskare.

  • CAD Model of a Gap in a Coplanar Waveguide
  • 1996
  • In: International Journal of Microwave and Millimeter-Wave Computer-Aided Engineering. - 1050-1827. ; 6:5, s. 369-377
  • Journal article (peer-reviewed)abstract
    • The partial capacitance approach and conformal mapping techniques are used to evaluate simple closed-form models for parallel and series capacitances of equivalent π-network of a symmetric gap in a CPW. Models are compared with experimental data and full wave analysis. They are useful for a wide range of CPW parameters and frequencies.

  • CAD models for multilayered substrate interdigital capacitors
  • 1996
  • In: IEEE Transactions on Microwave Theory and Techniques. - : Institute of Electrical and Electronics Engineers (IEEE). - 0018-9480 .- 1557-9670. ; 44:6, s. 896 - 904
  • Journal article (peer-reviewed)abstract
    • Conformal mapping-based models are given for interdigital capacitors on substrates with a thin superstrate and/or covering dielectric film. The models are useful for a wide range of dielectric constants and layer thicknesses. Capacitors with finger numbers n⩾2 are discussed. The finger widths and spacing between them may be different. The results are compared with the available data and some examples are given to demonstrate the potential of the models

  • Simple and accurate dispersion expression for the effective dielectric constant of coplanar waveguides
  • 1997
  • In: IEE Proceedings: Microwaves, Antennas and Propagation. - : Institution of Engineering and Technology (IET). - 1350-2417 .- 1359-706X. ; 144:2, s. 145-148
  • Journal article (peer-reviewed)abstract
    • A conformal mapping based analytic formula is proposed for computation of the frequency dependent effective dielectric constant, ɛeff, of coplanar waveguides (CPW). This formula is correct in a wide frequency band and for wide range of CPW parameters, and models both negative and positive slopes in the frequency dependence of ɛeff. The results are especially useful for modeling microwave/millimetrewave and ultrahigh speed digital interconnects.
