摘要：

The Cauchy method has been used to extrapolate a desired parameter over a broad range of frequencies. This information is generated using some information about the parameter at some discrete frequency points in a narrow range. The approach is to assume that the parameter is a rational function of frequency. The problem is to determine the order of the polynomials and the coefficients therein. The method of total least squares is used to solve the resulting matrix equation. This method can be coded as a stand-alone program for parameter extrapolation or incorporated as part of a larger analysis program. The Cauchy method has yielded accurate results when used in conjunction with a method-of-moments program and as an independent program in device characterization. (C) 1993 John Wiley & Sons, Inc.
