Efficient algorithms for computing Sommerfeld integral tails

Juan Ramon Mosig, Ruzica Golubovic

Sommerfeld-integrals (SIs) are ubiquitous in the analysis of problems involving antennas and scatterers embedded in planar multilayered media. It is well known that the oscillating and slowly decaying nature of their integrands makes the numerical evaluati ...

Isogeometric Analysis for Reduced Fluid-Structure Interaction Models in Haemodynamic Applications

Anna Tagliabue

Isogeometric analysis (IGA) is a computational methodology recently developed to numerically approximate Partial Differential Equation (PDEs). It is based on the isogeometric paradigm, for which the same basis functions used to represent the geometry are t ...

Novel Laminated Connections

Manuel Santarsiero

As an alternative to standard adhesive connections, the PhD research project ‘Novel Laminated Connections for Structural Glass Applications’, which recently started at the ICOM-EPFL, focuses on the use of polymer foil/interlayer materials to laminate (meta ...

Ziv-Zakai Lower Bound for Impulse Radio Ultra-WideBand Ranging Error Correlation Matrix

Jean-Yves Le Boudec, John Farserotu, Hai Zhan

We derive the Ziv-Zakai lower bound for Impulse Radio (IR) Ultra-WideBand (UWB) ranging error correlation matrix under a classical IR-UWB positioning system. We present the numerical evaluations with IEEE 802.15.4a channel model and the geometry of indoor ...

A numerical study of the influence of disorder in semiconductors on spin-Rabi nutation observed with pulsed electrically or optically detected magnetic-resonance techniques (pEDMR and pODMR, respectively) is presented. It is shown that transient nutation s ...

Mechanical stabilisation and design optimisation of masks for stencil lithography: Numerical approach and experimental validation

Jürgen Brugger, Andreea Veronica Savu, Marc Antonius Friedrich van den Boogaart

This paper addresses mask deformation phenomenon that frequently occurs but is highly undesirable in stencil lithography. Previously, a technique for mechanical stabilisation of stencils was proposed [M.A.F. van den Boogaart, et al., Corrugated membranes f ...
