On grouping individual wire segments into equivalent wires or chains, and introduction of multiple domain basis functions

Author: Lysko, Albert A Date: Jun 2009 The paper introduces a method to cover several wire segments with a single basis function, describes related practical algorithms, and gives some results. The process involves three steps: identifying chains of wire segments, splitting the ... Read more
Reducing condition number by appropriate current decomposition on a multiplet of several wires

Author: Lysko, Albert A Date: Jul 2011 This paper discusses a numerical investigation in connection with the dependency of the condition number of the impedance matrix on the decomposition of current on a junction with several attached wires (multiplet). It is shown that the ... Read more
Simple preconditioning technique: empirical formula for condition number reduction at a junction of several wires

Author: Lysko, Albert A Date: Aug 2011 The condition number for a method-of-moments’ impedance matrix resulting from a junction of several wires is frequency dependant and can be minimized at a given frequency using several approaches. An empirical formula for an optimum, ... Read more
Using piecewise sinusoidal basis functions to blanket multiple wire segments

Author: Lysko, Albert A Date: Jun 2009 This paper discusses application of the piecewise sinusoidal (PWS) basis function (BF) over a chain of several wire segments, for example as a multiple domain basis function. The usage of PWS BF is compared to results based on the piecewise ... Read more
