dc.description.abstractAn approach for designing antenna coupled infrared detectors (planar multimode detectors) for wavelength selectivity, and dielectric coated Salisbury Screen and Jaumann Absorber for wavelength selectivity and broad band absorption is presented. Calculations of electromagnetic behaviors of the designs and verifications are presented. These structures offer the possibility of wavelength selectivity or broad band absorption by tailoring its spectral responses. They also offer the possibility of increasing compactness to save space. We present diverse designs to achieve multi-color imaging, bolometers in parallel, vertically stacked bolometers, tuning by changing the distance between bolometric layer and mirror, tuning by lithographically drawn parameters, and so on. We also present thermally improved bolometer arrays to improve responsivity, detectivity, NEP, speed, and so on.
