Compression of the MoM matrix using macrobasis functions with a full-controlable accuracy

Author(s) : Tamayo Palau, José María , Heldring, Alexander , Rius Casals, Juan Manuel
Description : A new accuracy-controlable method for compressing the MoM impedance matrix of an electromagnetic problem based on a basis change plus a truncation with a threshold is presented here. The idea is to switch to singular basis functions, which are defined on relatively large subdomains of the object, re...

Taylor-orthogonal basis functions for the discretization in method of moments of second kind integral equations in the scattering analysis of perfectly conducting or dielectric objects

Author(s) : Úbeda Farré, Eduard , Tamayo Palau, José María , Rius Casals, Juan Manuel
Description : We present new implementations in Method of Moments of two types of second kind integral equations: (i) the recently proposed Electric-Magnetic Field Integral Equation (EMFIE), for perfectly conducting objects, and (ii) the Müller formulation, for homogeneous or piecewise homogeneous dielectric obje...

Zeroth-order divergence-complete discretizations of the EFIE at very low frequencies

Author(s) : Úbeda Farré, Eduard , Tamayo Palau, José María , Rius Casals, Juan Manuel
Description : We present the Self-Loop basis functions, an edge-oriented divergence-conforming set with zero charge density. These basis functions allow a rearrangement of the Linear-linear basis functions set to overcome the low-frequency breakdown of the Electric-field Integral Equation.

Accelerated direct solution of the MoM-VIE for dielectric scatterers

Author(s) : Heldring, Alexander , Tamayo Palau, José María , Rius Casals, Juan Manuel , Úbeda Farré, Eduard
Description : The Multiscale Compressed Block Decomposition algorithm (MS-CBD), a direct (non-iterative) linear solver, is applied to accelerate the solution of the MoM-VIE formulation for dielectric scatterers. Numerical solutions are presented for problems with several hundreds of thousands of unknowns. Asympto...

Very accurate computation of the impedance elements on the discretization of the magnetic field integral equation with the orthogonal basis functions

Author(s) : Tamayo Palau, José María , Úbeda Farré, Eduard , Polimeridis, Athanasios G. , Rius Casals, Juan Manuel , Mosig, Juan Ramón
Description : We show a novel integrating technique, the direct evaluation method, that provides maximum accuracy in the computation of the MFIE-interactions between neighboring noncoplanar basis functions sharing an edge or a vertex of the discretization. Unlike the previous techniques, this strategy requires no...

Fast direct solution of method of moments linear system

Author(s) : Heldring, Alexander , Rius Casals, Juan Manuel , Tamayo Palau, José María , Parrón Granados, Josep , Úbeda Farré, Eduard
Description : A novel algorithm, the compressed block decomposition (CBD), is presented for highly accelerated direct (non iterative) method of moments (MoM) solution of electromagnetic scattering and radiation problems. The algorithm is based on a block-wise subdivision of the MoM impedance matrix. Impedance mat...
