“…The higher order FEM results are compared with the solution obtained by an alternative FEM approach using a first-order brick mesh [4] (the number of unknowns is not reported in [4]) and with experimental results [10]. It can be observed that the solution obtained by means of the higher order FEM is in excellent agreement with both reference sets of results.…”

“…Along with the mode-matching (MM) technique [1], [2] and the method of moments (MoM) [3], the finite-element method (FEM) has proven to be a very powerful computational frame for analysis and characterization of multiport waveguide structures of arbitrary shapes and with arbitrary material complexities [4]- [8]. In addition to traditionally used low-order small-domain FEM tools, which employ electrically small finite elements (on the order of a tenth of the wavelength in each dimension) and low-order (zeroth and first order) basis functions for the approximation of fields, several novel FEM techniques based on curved elements for geometrical modeling and/or higher order basis functions for field modeling have recently been employed in analysis of arbitrary multiport waveguide structures [6]- [8].…”

Abstract-In this paper, the finite element method (FEM) is applied to the analysis of threedimensional (3D) electromagnetic structures. The incomplete Cholesky (IC) preconditioner based on shifted operators is used to solve the finite element linear systems. Several strategies are adopted to raise the efficiency and robustness of the preconditioner. Numerical experiments for several microwave devices demonstrate the superior numerical convergence and robustness of the proposed preocnditioner.

Scalability and low power consumption are major issues in designing custom hardware platforms for accelerating computation intensive electromagnetic applications. Clustered architectures decreases wire delays, power consumption and enhance scalability. We introduce a new steering algorithm that increases the performance of electromagnetic applications on such architectures, making clustering an even more attractive design alternative. The effectiveness of the new method is illustrated for two representative electromagnetic benchmarks.Index Terms-Clustered architectures, computational electromagnetics, hardware acceleration.
