Abstract (AI)
Abstract It is shown that thin mushroom layers (high‐impedance surfaces realized as regular arrays of small patches at a small distance from a metal surface) can be used as radar‐absorbing structures whose performance does not change with the incidence angle for TM‐polarized waves. The key role of the vias connectors between the patches and the ground plane is explained, and potential performance demonstrated in examples. © 2003 Wiley Periodicals, Inc.

Key Findings
1
Potential performance of the proposed structure is demonstrated through examples (designs or simulations) in the paper.
2
The absorber performance of these thin high-impedance surfaces does not change with incidence angle for TM-polarized waves.
3
Thin mushroom layers (high-impedance surfaces of small patch arrays close to a metal plane) can serve as radar-absorbing structures.
4
Vias connecting the patches to the ground plane play a key role in achieving the angle-independent absorption.
