Abstract
The use of a patterned resistive sheet acting as an infrared frequency-selective absorber is discussed. These patterned resistive sheets are a modified form of classical Salisbury Screens that utilize a resistive absorber layer placed a quarter-wavelength in front of a mirror. In contrast with previously designed planar antenna-coupled microbolometers that consist of both resistive and highly conductive metal strips (acting as antennas), the absorption layer in these structures involves a single resistive layer with patterned holes.
