Designing Aspects for Performance Optimization of Dual-Band Metamaterial Absorbers Useful for IR Camouflaging in Aeronautics

Kamal Nain Chopra*, Ritu Walia

This paper deals with the analytical treatment and unique characteristics of artificial dielectrics in the form of Dual-band metamaterial absorbers. The advantages of the metamaterials designed as Absorbers over the conventional absorbers have been discussed. The usefulness of such absorbers in various opto-electronic devices including Spatial light modulators and Infrared camouflaging in Aeronautics; and especially in Research areas has been highlighted. An attempt has been made to suggest a new approach for the fabrication of such absorbers by discussing the experimental aspects of the designing and coating techniques required in such work, which can be very useful for the optical engineers engaged in making these absorbers. The paper is expected to be useful for the researchers and optical and coating designers engaged in this novel evolving field of aeronautics and aeronautical engineering.
