MLFMM

Analysing a Pyramidal Horn Antenna with the MLFMM

A pyramidal horn is analysed with the MLFMM to obtain both near- and far-field plots. Results are compared to published literature.

Dual-Mode Circular Horn Simulation with the MLFMM

A dual-mode circular horn antenna is simulated with the MLFMM and far-fields are extracted.

Estimating the resource requirements for the MLFMM

The MLFMM is very suitable for solving electrically large problems. But exactly how large is a question users often ask. This document shows how to estimate the runtimes and memory requirements of a typical large problem given the resources for the same problem analyzed at a much lower frequency.

FEKO on EM64T

FEKO is made available on the new EM64T technology from Intel. The main advantage of this technology is that it supports both 32-bit and 64-bit applications. A 32-bit application has an inherent 2 GByte memory limitation. When using 64-bit technology the FEKO kernel does not suffer from this restriction, allowing the in-core solution of problems with more unknowns. (December 2004)

FEKO Quarterly - September 2007

Review of the release of FEKO 5.3 and the most prominent new features in this release.

First commercial release of Multi-Level Fast Multipole Method (MLFMM)

FEKO, introduces the Multi-Level Fast Multipole Method (MLFMM) to the market through Suite 4.2. Although the MLFMM has been researched at several research institutions for many years, FEKO is the first commercial code to bring it to the market for general 3D structures. The MLFMM is an efficient method of calculating the interaction between structures that are electrically far apart, retaining the accuracy of the method of moments, but enabling the analysis of significantly larger problems because much less memory is required. Applications include analysis of electrically large antennas, e.g. reflectors and antenna placement on large platforms, e.g. ships, automobiles and aircraft. (June 2004)
