Abstract

We discuss the design and optimization of the absorber for Terahertz Intensity Mapper, a balloon-borne kinetic inductance detector spectrometer. The novel “chain-link” absorber design offers excellent performance, independent optimization for both polarizations, and robust fabrication. Electromagnetic simulations indicate in-band absorption efficiency over ∼ 90 % in both linear polarization modes. DC measurements on different film thicknesses indicate the desired sheet resistance.
