Abstract

We present several designs for the infrared stand-off detection of passive chemo-sensing absorbers. Two absorbers are implemented as Salisbury Screen Absorbers (SSA) and the third design is implemented using a novel actuated Electromagnetic Band Gap (EBG) structure. Both approaches signal the presence of a chemical analyte via considerable changes in reflectivity. This change is subsequently detected by a thermal imaging camera which operates in the 8-12μm range. In addition to the ease of implementation that results from using ambient lighting, our designs feature a large contrast between states, scalability for long stand-off distances and a wide field of view (FOV). Both designs types are optimized for best performance via a Genetic Algorithm (GA) [1].
