Abstract :
A simple, least-squares sum curve fitting technique is presented which accurately models surface currents on planar transmission lines. This approach is useful for characterizing discontinuities occurring in MICs fabricated on dissipative substrates. Numerical results for the microstrip open end on a lossy GaAs substrate are given
