Phase-resolved visualization of radio-frequency standing waves in superconducting spiral resonator for metamaterial applications
A. A. Leha, A. P. Zhuravel, A. Karpov +2
Superconducting microcircuits and metamaterials are promising candidates for use in new generation cryogenic electronics. Their functionality is largely justified by the macroscopi…
Phase-sensitive imaging of microwave currents in superconductive circuits
A. Karpov, A. P. Zhuravel, A. S. Averkin +2
The contemporary superconductive electronics is widely using planar circuits with micrometer-scale elements for a variety of applications. With the rise of complexity of a circuit…
Superconductive Ultra-compact Magnetically Coupled Resonator with Twin-spiral Structure
A. S. Averkin, A. P. Zhuravel, A. Karpov +2
We describe a practical design of an ultra-compact on-chip superconductive micro-resonator as a potential magnetic element of metamaterial. The achieved resonator size with respect…
Electrodynamics of a planar Archimedean spiral resonator
N. Maleeva, N. N. Abramov, A. S. Averkin +4
We present a theoretical and experimental study of electrodynamics of a planar spiral superconducting resonator of a finite length. The resonator is made in the form of a monofilar…
Broadband Sample Holder for Microwave Spectroscopy of Superconducting Qubits
A. S. Averkin, A. Karpov, K. Shulga +5
We present a practical design and implementation of a broadband sample holder suitable for microwave experiments with superconducting integrated circuits at millikelvin temperature…
Electrodynamics of a ring-shaped spiral resonator
N. Maleeva, M. V. Fistul, A. Karpov +4
We present analytical, numerical and experimental investigations of electromagnetic resonant modes of a compact monofilar Archimedean spiral resonator shaped in a ring, with no cen…
Detection of OH and HO towards Orion~KL
H. Gupta, P. Rimmer, J. C. Pearson +76
We report observations of the reactive molecular ions OH, HO, and HO towards Orion KL with Herschel/HIFI. All three fine-structure transitions of OH…
Herschel observations of EXtra-Ordinary Sources: The Terahertz spectrum of Orion KL seen at high spectral resolution
N. R. Crockett, E. A. Bergin, S. Wang +60
We present the first high spectral resolution observations of Orion KL in the frequency ranges 1573.4 - 1702.8 GHz (band 6b) and 1788.4 - 1906.8 GHz (band 7b) obtained using the HI…
Herschel observations of extra-ordinary sources: Detecting spiral arm clouds by CH absorption lines
S. -L. Qin, P. Schilke, C. Comito +67
We have observed CH absorption lines () against the continuum source Sgr~B2(M) using the \textit{Herschel}/HIFI instrument. With the high spectral…
Herschel observations of ortho- and para-oxidaniumyl (H2O+) in spiral arm clouds toward Sgr B2(M)
P. Schilke, C. Comito, H. S. P. Mueller +55
H2O+ has been observed in its ortho- and para- states toward the massive star forming core Sgr B2(M), located close to the Galactic center. The observations show absorption in all…
