radar-absorbing material[′rā‚där əb‚sȯrb·iŋ mə‚tir·ē·əl]
A material that is designed to reduce the reflection of electromagnetic radiation by a conducting surface in the frequency range from approximately 100 megahertz to 100 gigahertz.
Various composites that greatly reduce the strength of RF (radio frequency) energy reflected back along the incident path. Besides the composites, a number of radar-absorbing paints also give similar properties to the basic aircraft materials, although they are not as efficient as radar-absorbing materials.
