This paper presents a new design of an absorbing screen based on a classical Salisbury concept. In the new design a resistive sheet from the classical Salisbury screen is replaced by a patterned layer. This allows eliminating major disadvantages of classical solutions, such as their narrow frequency bandwidth and high overall screen thickness. Electromagnetic simulations with QuickWave - 3D package are performed and confirm the theoretical predictions of the paper.

Artykuł prezentuje nowe podejście do struktur absorbujących, oparte o klasyczne rozwiązanie typu Salisbury. W zaproponowanej strukturze, jednorodna warstwa rezystywna zastąpiona została przez warstwę wzorów. Takie rozwiązanie pozwala na wyeliminowanie głównych wad klasycznych struktur, którymi są wąskie pasmo pracy oraz duża grubość panelu. Symulacje elektromagnetyczne potwierdzające słuszność przyjętej koncepcji, przeprowadzono w programie QuickWave - 3D.
