We examine the unusual dispersion and attenuation of transverse electromagnetic waves in the few-THz regime on nanoscale graphene and copper transmission lines. Conventionally, such propagation has been considered to be highly dispersive, due to the RC time constant-driven voltage diffusion below 1 THz and plasmonic effects at higher optical frequencies. Our numerical modeling across the microw...
A large community has converged on the idea of using high quality factor superconducting microresonators to achieve dense frequency domain multiplexing at microwave frequencies. This technique uses wide bandwidth high electron mobility transistors (HEMTs) to provide several GHz of bandwidth with noise temperatures below 5 Kelvin, potentially allowing thousands of detectors to be read out throug...
SuperSpec is an ultra-compact spectrometer-on-a-chip for mm and submm wavelength astronomy. Its very small size, wide spectral bandwidth, and highly multiplexed detector readout will enable construction of powerful multi-object spectrometers for observations of galaxies at high redshift. SuperSpec is a filter bank with planar, lithographed, superconducting transmission line resonator filters an...
The fundamental excitations in superconductors - Bogoliubov quasiparticles can be either a resource or liability superconducting devices: they are what enables photon detection microwave kinetic inductance detectors, but source of errors qubits and electron pumps. To improve operation the latter devices, ways to mitigate quasiparticle effects have been devised; particular, combining different m...
We present an updated design of the 220 GHz microwave kinetic inductance detector (MKID) pixel for SPT-3G+, next-generation camera South Pole Telescope. show results dark testing a 63-pixel array with mean inductor quality factor $Q_{i} = 4.8 \times 10^{5}$</tex-m...
Context. Current generation millimeter wavelength detectors suffer from scaling limits imposed by complex cryogenic readout electronics. These instruments typically employ multiplexing ratios well below a hundred. To achieve multiplexing ratios greater than a thousand, it is imperative to investigate technologies that intrinsically incorporate strong multiplexing. One possible solution is the k...
