Abstract
The general Chebyshev approximation method is used to find the optimal solution to the Jaumman absorber problem. The Chebyshev-like (CL) solution with all reflection zeros at real frequencies is used as a starting point in the iteration. The optimal solution, with the reflection zeros moved slightly off the imaginary S-axis, is in the immediate vicinity of the CL-solution, and convergence properties are good.<>
