Application of the multilevel decomposition algorithm to the frequency analysis of large microstrip antenna arrays

Author(s) : Parrón Granados, Josep , Rius Casals, Juan Manuel , Mosig, Juan R.
Description : The application of integral equation methods based in the method of moments discretization to solve large antenna arrays is difficult due to the fact that the computational requirements increase rapidly with the number of unknowns. This is critical when a frequency analysis of the antenna is require...

New block ILU preconditioner scheme for numerical analysis of very large electromagnetic problems

Author(s) : Heldring, Alexander , Rius Casals, Juan Manuel , Ligthart, Leo P.
Description : Large electromagnetic scattering and radiation problems are tackled by iterative solvers, which require the use of huge preconditioners. Most often, the incomplete LU decomposition (ILU) of the preconditioner is applied to the system matrix at each iteration. However, the preconditioner ILU cannot b...

Method of moments enhancement technique for the analysis of Sierpinski pre-fractal antennas

Author(s) : Parrón Granados, Josep , Romeu Robert, Jordi , Rius Casals, Juan Manuel , Mosig, Juan R.
Description : The numerical analysis of highly iterated Sierpinski microstrip patch antennas by method of moments (MoM) involves many tiny subdomain basis functions, resulting in a very large number of unknowns. The Sierpinski pre-fractal can be defined by an iterated function system (IFS). As a consequence, the ...
