A computation of fin-line impedence

Abstract

The spectral domain solution for the wavelength and characteristic impedance of a millimeter wave fin-line was miginally published by Knorr and Shayda. The dispersion squations were subsequently reformulated by Knorr in a form more suitable for numerical computation. This thesis presents a reformulation of the equations for characteristic impedance for the same purpose. The equations have been used to implement a computer program, FINIMP. The program runs smoothly without the overflow and underflow problems experienced by Knorr and Shayda. FINIMP data is compared with other existing data and good agreement is shown to establish the correctness of the FINIMP numerical results.
