Abstract
The electric screen Jauman absorber [1] is a stratified cascade of die lectric spacers, interlaced with resistive sheets, which is effective in reducing specular reflection from flat or moderately curved conduct ing surfaces. A literature survey of the period up to 1993 may be foun d in [2], while the topic has also received more recent attention, e.g ., [3]-[9], Usually, the dielectric constant of the identical spacers is assumed known a priori, and the design problem is to find the sheet surface resistivities that will yield an absorption behavior which me ets certain design criteria, This paper presents detail on three effic ient and dedicated synthesis algorithms that synthesize absorbers with Butterworth, Equiripple, and Chebyshev absorption properties and shou ld be seen as complementary to the introductory discussion in [2], To the authors' knowledge, the Chebyshev solutions solve the fundamental problem for the first time.
