Conference Paper

Results of an investigation into the design of Jaumann absorbers are reported. Jaumann absorbers are effective in minimizing plane wave reflection from a conducting metal surface and exhibit reasonably wide frequency and incidence angle bandwidths. The spacers between the resistive sheets are usually assumed to be lossless and a quarter-wavelength long at the center frequency. It is shown that the numerical minimization technique can result in a design which improves upon the purely analytical methods. Some representative results are shown.
