We present the results of theoretical analysis and characteristics optimization for ultra-thin resonant absorbers based on artificial impedance surfaces, which are promising for using as the radiation-sensitive layers in selective bolometric detectors operating in the range of submillimeter waves. The key parameters of the ultra-thin absorbers, such as the absorption resonance Q-factor, the ratio of the peak absorptivity wavelength to the absorber thickness and the impedance surface unit cell size, are traced versus a geometric shape of the resonant elements and their electrical conductivity.
