Abstract :
Multimode microbolometers for wavelength-selective infrared detection have been designed using a genetic algorithm and an electromagnetic model of the planar antenna. Wavelength selectivity can be varied by changing lithographically drawn parameters, with bandwidth narrower than Fabry-Perot microbolometers. The design of a three-colour system covering the 7-14 μm band is presented.
