Absorber Design and Optimization of Kinetic Inductance Detectors for the Terahertz Intensity Mapper
Journal of low temperature physics(2022)
摘要
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 $$\sim 90\%$$ in both linear polarization modes. DC measurements on different film thicknesses indicate the desired sheet resistance.
