The design of Jauman absorbers

The paper presents a critical review of available solutions and design techniques. It then outlines three new and efficient algorithms, dedicated to the Jauman problem, which synthesize absorbers with Butterworth, equiripple or Chebyshev absorption characteristics'. Upper limits exist on the spacer dielectric constant for these solutions to be realizable, and are tabulated. An example of the results obtained, in the form of a design table for practical Chebyshev absorbers, is also presented. These designs are optimal in the sense of maximum bandwidth for fixed passband reflection coefficient magnitude.<
