NASA's EXperiment for Cryogenic Large-Aperture Intensity Mapping (EXCLAIM), is a balloon-borne instrument that designed to perform intensity mapping of CO and CII at redshifts as high z=3.5. It will map galaxy star formation history over cosmological time. EXCLAIM also demonstrate novel integrated silicon spectrometers using microwave kinetic inductance detectors (MKIDs) could be an enabling te...

We simulate the performance of a new type of instrument, a Superconducting Multi-Object Spectrograph (SuperMOS), that uses Microwave Kinetic Inductance Detectors (MKIDs). MKIDs, a new detector technology, feature good QE in the UVOIR, can count individual photons with microsecond timing accuracy and, like X-ray calorimeters, determine their energy to several percent. The performance of Giga-z, ...

Magnetic-field-resilient superconducting coplanar waveguide (SCPW) resonators are essential for developing integrated quantum circuits. Molybdenum–Rhenium (MoRe), which is a disordered alloy forming highly transparent contact to the graphene and carbon nanotubes, would be promising platform realizing field-resilient SCPW combined with nano-hybrid devices. We fabricated MoRe investigated their m...

A promising candidate for the next generation of microwave power devices, AlGaN/GaN HEMT has aroused numerous research interests due to its inherent high power characteristic. It has been studied intensively as high power microwave devices for satellite communication systems and in recent years, many GaN-based HEMTs have been reported for power amplification applications at Ka-band [13]. High g...

We present numerical simulations and microwave measurements on a loop-wire structure that acts as an effective medium exhibiting a well-defined bulk plasma frequency in the microwave regime, with an effective negative dielectric function below this plasma frequency. The dependence of this plasmonic response on the self-inductance of the constituent wire elements is made explicit. A finite struc...

The South Pole Telescope Summertime Line Intensity Mapper (SPT-SLIM) is a pathfinder experiment that will demonstrate the use of on-chip filter-bank spectrometers for mm-wave line intensity mapping (LIM). SPT-SLIM focal plane consists 18 dual-polarization R=300 covering 120-180 GHz, coupled to aluminum kinetic inductance detectors. A compact cryostat holds detectors at 100 mK and performs obser...
