  • Patent number: 5688348
    Abstract: 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.
    Type: Grant
    Filed: January 8, 1997
    Date of Patent: November 18, 1997
    Assignee: Northrop Grumman Corporation
