The reduced basis method for the electric field integral equation
Jan Sickmann Hesthaven, Bernhard Stamm
We introduce the reduced basis method (RBM) as an efficient tool for parametrized scattering problems in computational electromagnetics for problems where field solutions are computed using a standard Boundary Element Method (BEM) for the parametrized elec ...
ACADEMIC PRESS INC ELSEVIER SCIENCE2011Efficient machine precision computation of impedance matrix elements in surface integral equation formulations
The direct evaluation program tailored to the singular integrals arising in the first-kind and second-kind Fredholm surface integral equation formulations is presented. The exponential convergence of the proposed technique can safely guarantee the inherite ...
2011On the direct evaluation of surface integral equation impedance matrix elements involving point singularities
The direct evaluation method tailored to the 4-D singular integrals over vertex adjacent triangles, arising in the first-kind and second-kind Fredholm surface integral equation formulations, is presented. A combination of singularity cancellation, reorderi ...
Institute of Electrical and Electronics Engineers2011Incremental model identification for homogeneous systems – A comparison
Dominique Bonvin, Michael Amrhein, Nirav Pravinbhai Bhatt
The identification of reaction kinetics involves the determination of a model structure (reaction stoichiometry, rate laws for all reactions) and its corresponding parameters from experimental data. An incremental identification approach for determining th ...
2011Incremental Identification of Reaction and Mass-Transfer Kinetics Using the Concept of Extents
Dominique Bonvin, Michael Amrhein, Nirav Pravinbhai Bhatt
This paper proposes a variation of the incremental approach to identify reaction and mass-transfer kinetics (rate expressions and the corresponding rate parameters) from concentration measurements for both homogeneous and gas-liquid reaction systems. This ...
2011Bifurcation and decay of solutions for a class of elliptic equations on R-N
We consider a class of nonlinear eigenvalue problems including equations such as −Δu(x) + q(x)u(x) + γ u(x)2 ξ(x)2 + u(x)2 u = λu(x) for x ∈ R , where γ > 0, q ∈ L∞(RN ) and ξ ∈ L2(RN ) are given and we are interested in eigenvalues λ ∈ R for which this eq ...

In this paper, propagation losses effects present in rectangular waveguide structures are rigorously considered. For this purpose, a new formulation based on the perturbation of the boundary conditions on the metallic walls of the waveguides combined with ...
