Developments and advances in nonlinear terahertz spectroscopy
… antenna gaps. Impact ionization was observed in high-resistivity silicon, a material in which no nonlinear THz response had been previously seen, using metamaterial structures to enhance free space THz electric fields. Using three-dimensional metamaterial structures, the THz magnetic field is …

Fabrication of Superconducting Reflectionless Filters for Quantum Microwave Circuits
… thermal noise are essential for achieving high-fidelity readout and preserving qubit coherence. A significant challenge arises from the use of conventional cryogenic components such as isolators and circulators, which exhibit nonideal out-of-band reflection characteristics. Reflections …

Investigation of performance and the influence of environmental conditions on strip detectors for the ATLAS Inner Tracker Upgrade
… of the Large Hadron Collider (LHC) to the High-Luminosity LHC (HL-LHC) scheduled for installation in 2024, the Inner Detector will be replaced with the new all-silicon ATLAS Inner Tracker (ITk) to maintain tracking performance in this high-occupancy environment and to cope with the increase …

Three-Dimensional Heterogeneous Integration for RF/Microwave Applications
High performance RF/mixed signal systems require new interconnect strategies to combine high frequency (microwave/mm-wave) circuitry with silicon mixed-signal and baseband digital processing. In such systems, heterogeneous vertical integration, in which circuits in different technologies can be …

Superconducting Microwave Resonators for Low Loss Sensor Applications
… resonators that are very low in loss to create highly sensitive kinetic inductance detectors (KIDs). The multiplexing of hundreds of KIDs into arrays has already been successful in imaging red-shifted galaxies and CO lines. How- ever, to create arrays for lower frequency (sub-100 GHz) and lower …
