Fast Algorithms and Hybrid Techniques

“…The corresponding formulation can be obtained by applying the Laplace transform to the frequency -domain formulation [107,108] . The corresponding formulation can be obtained by applying the Laplace transform to the frequency -domain formulation [107,108] .…”

A hybrid Boundary Element Unstructured Transmission-line (BEUT) method for accurate 2D electromagnetic simulation

“…This is overcome by hybridizing with an efficient integral equation technique, as suggested in [16,17] for FDTD-BEM solvers, and [18,19] for FEM-BEM solvers. Also, the transmission line description of the low frequency response of the domain automatically guarantees stability during runtime, i.e.…”

Simulation of the mutual couplings among multiple antennas on large platform using multi-region multi-solver domain decomposition

“…Clearly, applying any single CEM method for the entire problem will inevitably cost tremendously more computational resources and incapable of treating every part of the problem domain efficiently. To alleviate this difficulty, some pioneering work [1] was proposed to solve the radiation and scattering of antenna mounted on large conducting platform using FEM-BI hybridazation. And a more general scheme was given in [2] and [3] to decompose the computational domain and solve each sub-region with different solver.…”
