    • An EMR-absorbing anechoic chamber absorber (22, 42) uses a block of honeycomb material with a lossy material, such as carbon, applied to the sheets (4) of material from which the honeycomb is made to create wedges (36) or pyramids (44) of lossy material. Preferably, the lossy material is applied to the sheets of material in a repeating wedge-shaped pattern (16) to create the wedges of lossy material within the solid rectangular block of honeycomb material. Parallel, wedge-shaped grooves (43) are formed in the block of honeycomb material to create the pyramids of lossy material. If the lossy material is applied to the entire sheet, a set of parallel, wedge-shaped grooves are formed in the block of honeycomb material to create wedges of lossy material; two sets of parallel, wedge-shaped grooves are formed at 90.degree. angles to one another to create pyramids of lossy material.
    • 吸收EMR的消声室吸收器(22,42)使用具有诸如碳的有损材料的蜂窝体材料块,其被施加到材料的片材(4)上,蜂窝材料制成楔形物(36)或金字塔 (44)有损材料。 优选地,将有损耗的材料以重复的楔形图案(16)施加到材料片上,以在蜂窝材料的实心矩形块内产生有损耗材料的楔形物。 在蜂窝状材料块中形成平行的楔形槽(43),以形成有损材料的金字塔。 如果将损耗材料施加到整个片材上,则在蜂窝材料块中形成一组平行的楔形槽,以形成有损耗材料的楔形物; 两组平行的楔形槽形成为彼此成90度角,形成有损材料的金字塔。
