Partial Element Equivalent Circuit (PEEC) Toolbox for MATLAB, integrating FastCap2 and FastHenry2 to Calculate Partial Elements, and Multisim or LTspice for circuit simulation

摘要

Partial Element Equivalent Circuit (PEEC) method is one of numerical modeling methods for solving electromagnetic problems. Electromagnetic problem to be solved is expressed with electric circuit, and then solved by some standard circuit solver software. To make working on PEEC method more accessible, a PEEC toolbox for MATLAB is created. Toolbox contains functions for describing and composing geometry of problem with wire-based language, functions for meshing according to PEEC requirements for surface and volume cells, functions for plotting geometry and mesh data. Specific functions enable using FastCap2 and FastHenry2 to calculate partial elements and getting data back. With toolbox functions one can create Netlist for interfacing with circuit simulation software, Multisim from National Instruments or LTspice from Linear Technology. Toolbox may serve as powerful Front-End for FastCap2 and FastHenry2.
