Abstract:
A method of modeling a circuit element comprising:a) discretizing said circuit element into at least one segment of a plurality of segments; b) dividing each segment of a plurality of segments into a plurality of filaments; c) providing an impedance matrix representative of said plurality of filaments, wherein said impedance matrix comprises: a first submatrix a11=R; a second submatrix a12=âˆ’&ohgr;L; a third submatrix a21=&ohgr;L; a fourth submatrix a22=R; and wherein R is a diagonal filament resistance matrix, L is a filament inductance matrix and &ohgr; is radian frequency; d) evaluating an equation M1=[&ohgr;2L(1/R)L+R]âˆ’1; e) evaluating a second matrix equation M2, wherein said matrix equation M2 comprises M1, L, 1/R, and &ohgr;; and f) optionally constructing said inverse of an impedance matrix by setting a first submatrix of said inverse c11=M1, a second submatrix of said inverse c12=M2, a third submatrix of said inverse c21=âˆ’M2, a fourth submatrix of said inverse c22=M1.
