  3. 3. Computation of EMC Properties of Slots and Printed Circuit Boards

    University dissertation from Chalmers University of Technology

    Author : Jan Carlsson; Chalmers tekniska högskola.; Chalmers University of Technology.; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics; chokes; corrugations; crosstalk; EFIE; electric field integral equation; EMC analysis; FDTD; Finite Difference Method; MM; MoM; Method of moments; PCB; printed circuit board; radiated emission; radiated susceptibility; slot; soft and hard surfaces; spectral domain; transmission line network; transmission line theory;

    Abstract : This thesis deals with the numerical solution of electromagnetic compatibility (EMC) problems for electronic systems, such as radiated emission, susceptibility and crosstalk on printed circuit boards and transmission through slots. The analysis of printed circuit boards is done by using an electric field integral equation (EFIE) expressed in the frequency domain, which is solved by using the method of moments. READ MORE

  5. 5. Model on Demand : Algorithms, Analysis and Applications

    University dissertation from Linköping : Linöping University

    Author : Anders Stenman; Linköpings universitet.; Linköpings universitet.; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : System identification deals with the problem of estimating models of dynamical systems from observed data. In this thesis, we focus on the identification of nonlinear models, and, in particular, on the situation that occurs when a very large amount of data is available. READ MORE
