Frequency selective surface (original) (raw)

About DBpedia

频率选择表面(Frequency Selective Surface),是一种薄的、周期性的介质面(例如微波炉的炉门),用来反射、透射或吸收一定频率的电磁波。可以说频率选择面是一种光学滤波器,其滤波功能是通过频率选择表面上的规则的、周期的图案(通常是金属,有时是电介质)来实现的。根据频率选择面的结构,频率选择面还具有随入射角和极化性质发生变化的特性。频率选择表面已被广泛应用于射频领域,还在微波炉、天线罩和超材料上有广泛应用。有时频率选择面也被简称为周期面。

dbo:abstract Als frequenzselektive Oberfläche (engl. frequency selective surface, abgekürzt FSS) bezeichnet man Flächen, die elektromagnetische Strahlung frequenzabhängig reflektieren, insbesondere im Radiofrequenzbereich bis zu einigen GHz. FSS-Beschichtungen können einzelne Frequenzen ausblenden, beispielsweise um Störungen durch einen starken Sender zu unterdrücken, ohne gleichzeitig den Empfang aller Sender zu verhindern. Ein durchstimmbares Radar kann anhand der FSS-Reflexionsmuster Flugobjekte unterscheiden. Im Frequenzbereich des sichtbaren Lichts sind solche Flächen nichts Besonderes, da einfaches Einfärben eine Frequenzselektion hervorruft. (de) A frequency-selective surface (FSS) is any thin, repetitive surface (such as the screen on a microwave oven) designed to reflect, transmit or absorb electromagnetic fields based on the frequency of the field. In this sense, an FSS is a type of optical filter or metal-mesh optical filters in which the filtering is accomplished by virtue of the regular, periodic (usually metallic, but sometimes dielectric) pattern on the surface of the FSS. Though not explicitly mentioned in the name, FSS's also have properties which vary with incidence angle and polarization as well - these are unavoidable consequences of the way in which FSS's are constructed. Frequency-selective surfaces have been most commonly used in the radio frequency region of the electromagnetic spectrum and find use in applications as diverse as the aforementioned microwave oven, antenna radomes and modern metamaterials. Sometimes frequency selective surfaces are referred to simply as periodic surfaces and are a 2-dimensional analog of the new periodic volumes known as photonic crystals. Many factors are involved in understanding the operation and application of frequency selective surfaces. These include analysis techniques, operating principles, design principles, manufacturing techniques and methods for integrating these structures into space, ground and airborne platforms.
