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.
