Pilot: a Fast Algorithm for Enhanced 3d Parasitic Capacitance Extraction Efficiency

Integral-equation methodologies applied to extract parasitics for board, package, and on-chip structures involve solving a dense system of equations. In this paper, we present an improved matrix-compression technique for fast iterative solution of such dense systems, which applies QR decomposition on multilevel oct-tree-based interaction sub-matrices. The regular-tree structure of the fast-mult...

A Comparative Study of Multipole and Empirical Relations Methods for Effective Index and Dispersion Calculations of Silica-Based Photonic Crystal Fibers

In this paper, we present a solid-core Silica-based photonic crystal fiber (PCF) composed of hexagonal lattice of air-holes and calculate the effective index and chromatic dispersion of PCF for different physical parameters using the empirical relations method (ERM). These results are compared with the data obtained from the conventional multipole method (MPM). Our simulation results reveal tha...

The fast multipole boundary element method for potential problems: A tutorial

The fast multipole method (FMM) has been regarded as one of the top 10 algorithms in scientific computing that were developed in the 20th century. Combined with the FMM, the boundary element method (BEM) can now solve large-scale problems with several million degrees of freedom on a desktop computer within hours. This opened up a wide range of applications for the BEM that has been hindered for...

Multi-Level Fast Multipole Algorithm for General Targets on a Half-Space Interface

The multi-level fast multipole algorithm (MLFMA) is considered for scattering from an electrically large conducting or dielectric target resting on the interface of a dielectric half space. We focus on analysis of the half-space Green’s function such that it is computed efficiently and accurately, while retaining a form that is applicable to an MLFMA analysis. Attention is also directed toward ...

Improved Interpolation of Evanescent Plane Waves for Fast Multipole Methods

One way to implement a low-frequency or broadband fast multipole method is to use the spectral representation, or inhomogeneous plane-wave expansion, of the Green’s function. To significantly improve the error-controllability of the method, we propose a new interpolation and anterpolation scheme for the evanescent part. DOI: 10.2529/PIERS060907051636 The fast multipole method (FMM) can be used ...
