(author), Murugesan, Vignesh (author), Thoen, David (author), Neto, A. (author), Baselmans, J.J.A. (author)We present the design, fabrication, and characterization of a broadband leaky lens antenna for broadband, spectroscopic imaging applications. The antenna is designed for operation in the 300-900 GHz band. We integrate the antenna directly into an Al-NbTiN hybrid microwave kinetic inductance detector (MKID) to measure the beam pattern and...journal article 2020

van Berkel, S.L. (author), Yurduseven, O. (author), Freni, Angelo (author), Neto, A. (author), Llombart, Nuria (author)In millimeter and submillimeter-wave radiometric imaging systems, a persistent goal is the increase in the speed of acquisition of the image while maintaining a high sensitivity. Typically, the highest sensitivity is achieved by cryogenically cooling the detectors, specifically in astronomical applications. However, for the purpose of low...journal article 2017
