Weighted Averages and Double Exponential Algorithms

Juan Ramon Mosig

This paper reviews two simple numerical algorithms particularly useful in Computational ElectroMagnetics (CEM): the Weighted Averages (WA) algorithm and the Double Exponential (DE) quadrature. After a short historical introduction and an elementary descrip ...

Algorithm to calculate a large number of roots of the cross-product of Bessel functions

Juan Ramon Mosig, Michael Mattes, Francisco Edén Sorolla Rosario

This paper describes an algorithm to calculate a large number of roots of the cross-product of Bessel functions and of their first derivatives. The algorithm initially finds the roots of the zeroth order using an auxiliary function that exhibits the same r ...

Extended SIW for TEm0 and TE(0)n Modes and Slotline Excitation of the TE01 Mode

Juan Ramon Mosig, Jean-François Zürcher, Benjamin Fuchs, Marc Esquius Morote

A substrate integrated guide which allows the propagation of both TEm0 and TE0n modes is presented, the Extended Substrate Integrated Waveguide (ESIW). Its structure combines the working principles of SIWs and SINRD guides. While the performances of the ES ...

DIRECTFN: Fully Numerical Algorithms for High Precision Computation of Singular Integrals in Galerkin SIE Methods

Juan Ramon Mosig

Fully numerical schemes are presented for high precision computations of the four-dimensional integrals arising in Galerkin surface integral equation formulations. More specifically, the focal point of this paper is the singular integrals for coincident, e ...

Analytical shape derivatives of the MFIE system matrix discretized with RWG functions

Juan Ramon Mosig, Athanasios Polymeridis

An analytical formula for the shape derivative of the magnetic field integral equation (MFIE) method of moments (MoM) system matrix (or impedance matrix) is derived and validated against finite difference formulas. The motivation for computing the shape de ...

Analysis of human brain exposure to low-frequency magnetic fields: A numerical assessment of spatially averaged electric fields and exposure limits

Juan Ramon Mosig, Nicolas Chavannes, Valerio De Santis

Compliance with the established exposure limits for the electric field (E-field) induced in the human brain due to low-frequency magnetic field (B-field) induction is demonstrated by numerical dosimetry. The objective of this study is to investigate the de ...

Integral Equation Analysis of Plane Wave Scattering by Coplanar Graphene-Strip Gratings in the THz Range

Juan Ramon Mosig, Julien Perruisseau-Carrier, Juan Sebastian Gomez Diaz

The plane wave scattering and absorption by finite and infinite gratings of free-space standing infinitely long graphene strips are studied in the THz range. A novel numerical approach, based on graphene surface impedance, hyper-singular integral equations ...

Broadband Ka-band rectangular waveguide to substrate integrated waveguide transition

Juan Ramon Mosig, Jean-François Zürcher, Rafal Glogowski

A simple right-angle transition between a rectangular waveguide (RWG) and a substrate integrated waveguide (SIW) is proposed. Two slots etched on the broad wall of the SIW are used to couple the waveguides. To obtain a wide bandwidth of operation the slots ...

Analyzing Corona breakdown with a finite element-based electromagnetic solver

Juan Ramon Mosig, Michael Mattes, Francisco Edén Sorolla Rosario, Ioannis Koufogiannis

This paper demonstrates how an already developed finite element code for solving electromagnetic problems can be manipulated and simply extended so as to investigate complicated corona breakdowns. A safe criterion based on the eigenvalue analysis is used i ...

Synthesis of uniform amplitude focused beam arrays

Juan Ramon Mosig, Anja Skrivervik, Benjamin Fuchs

An iterative algorithm to synthesize uniform amplitude focused beam arrays is presented. While the number of array elements and the excitations are fixed and known, the locations of the elements are optimized to radiate a narrow beam low sidelobe pattern. ...

The weighted averages algorithm revisited

Juan Ramon Mosig

The classic weighted averages (WA) algorithm for the evaluation of Sommerfeld-like integrals is reviewed and reappraised. As a result, a new version of the WA algorithm, called generalized WA, is introduced. The new version can be considered as a generaliz ...
