  2. 16. Boundary and Interface Conditions for Electromagnetic Wave Propagation using FDTD

    Author : Jon Häggblad; Björn Engquist; Olof Runborg; Thomas Rylander; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Numerical analysis; Numerisk analys;

    Abstract : Simulating electromagnetic waves is of increasing importance, for example, due to the rapidly growing demand of wireless communication in the fields of antenna design, photonics and electromagnetic compatibility (EMC). Many numerical and asymptotic techniques have been developed and one of the most common is the Finite-Difference Time-Domain (FDTD) method, also known as the Yee scheme. READ MORE

  4. 17. Measurements and analysis of electromagnetic interferences in the Swedish railway systems

    Author : Stefan Niska; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : Presently, the existing failure reporting system at Banverket (the Swedish Rail Administration), which handles reports on the failures of the railway infrastructures and possible causes of failure, is not optimum (or most suitable) when it comes to analysis of electromagnetic compatibility (EMC)- related failures and causes. This failure reporting system is reliant on correct reporting into the system, so that the right information can be sent back to the users, the maintenance and service personnel, in real time.

  5. 18. Electromagnetic Interference in Modern Electrified Railway Systems with Emphasis on Pantograph Arcing

    Author : Surajit Midya; Uppsala universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Electrified railways are undergoing rapid modernized in terms of increased speed, freight capacity and increased traffic. Traction systems are spread across countries with different signaling and power feeding systems. Signalling systems are undergoing modernization and now-a-days are more dependent on wireless and radio based services. READ MORE

  6. 19. Broadband Electromagnetic Scattering and Shielding Analysis using the Finite-Difference Time-Domain Method

    Author : Torleif Martin; Anders Bondeson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis deals with numerical simulations of Maxwell's equations using the Finite-Difference Time-Domain (FDTD) method. The method is widely used in scattering, antenna and electromagnetic compatibility (EMC) applications. READ MORE

  7. 20. Co-Simulation of Coupled Electromagnetic and Nonlinear Circuit Problems using the Partial Element Equivalent Circuit Method

    Author : Sohrab Safavi; Wil Schilders; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Abstract : Co-simulation of coupled electromagnetic (EM) structures and linear/nonlinear circuits has become a major demand in today's engineering. In many disciplines such as antenna engineering, microwave circuit design, electromagnetic compatibility (EMC), and even fairly low-frequency power electronic systems, simulation techniques capable of incorporating both EM structures and lumped circuit elements have become a necessity.
