Partially Transparent Jaumann-Like Absorber Applied to a Curved Structure
A Jaumann absorber with its metal backing replaced with a combined low-pass and polarizer FSS is investigated with respect to its absorption and its polarization-dependent low-frequency transparency properties. This structure is applied to an idealized curved wing-front end, and its monostatic radar...

| description | A Jaumann absorber with its metal backing replaced with a combined low-pass and polarizer
FSS is investigated with respect to its absorption and its polarization-dependent low-frequency transparency properties. This structure is applied to an idealized curved wing-front end, and its monostatic
radar cross-section is determined. The FSS-Jaumann structure preserves an absorption similar to
the planar Jaumann absorber in the higher frequency interval and enables a partial transparency in
the TEz polarization at 1 GHz. In addition, once the structure is applied to the wing-front end, a
significant reduction in two-dimensional radar cross-section for both the TMz and TEz polarization
over 2–16 GHz is observed. A sensitivity analysis shows that the resistivity of the inner resistive layer
has a large impact on the 1 GHz transmission. |
