An efficient full wave solver for eddy currents
Johan Helsing, Anders Karlsson, Andreas Rosén
An integral equation reformulation of the Maxwell transmission problem is presented. The reformulation uses techniques such as tuning of free parameters and augmentation of close-t…
Comparison of integral equations for the Maxwell transmission problem with general permittivities
Johan Helsing, Anders Karlsson, Andreas Rosén
Two recently derived integral equations for the Maxwell transmission problem are compared through numerical tests on simply connected axially symmetric domains for non-magnetic mat…
An extended charge-current formulation of the electromagnetic transmission problem
Johan Helsing, Anders Karlsson
A boundary integral equation formulation is presented for the electromagnetic transmission problem where an incident electromagnetic wave is scattered from a bounded dielectric obj…
On a Helmholtz transmission problem in planar domains with corners
Johan Helsing, Anders Karlsson
A particular mix of integral equations and discretization techniques is suggested for the solution of a planar Helmholtz transmission problem with relevance to the study of surface…
Resonances in axially symmetric dielectric objects
Johan Helsing, Anders Karlsson
A high-order convergent and robust numerical solver is constructed and used to find complex eigenwavenumbers and electromagnetic eigenfields of dielectric objects with axial symmet…
Determination of normalized electric eigenfields in microwave cavities with sharp edges
Johan Helsing, Anders Karlsson
The magnetic field integral equation for axially symmetric cavities with perfectly conducting piecewise smooth surfaces is discretized according to a high-order convergent Fourier-…
