Electromagnetic absorbers
Electromagnetic absorbers are specifically chosen or designed materials that can inhibit the reflection or transmission of electromagnetic radiation. For example, this can be accomplished with materials such as dielectrics combined with metal plates spaced at prescribed intervals or wavelengths. The particular absorption frequencies, thickness, component arrangement and configuration of the materials also determine capabilities and uses. In addition, researchers are studying advanced materials such as metamaterials in hopes of improved performance and diversity of applications. Some intended applications for the new absorbers include emitters, sensors, spatial light modulators, infrared camouflage, wireless communication, and use in thermophotovoltaics.
