چکیده
Background: Kinetic Inductance Travelling Wave Parametric Amplifiers (KITWPAs) are a new variant of superconducting amplifier that can potentially achieve high gain with quantum-limited noise performance over broad bandwidth, which is important for many ultra-sensitive experiments. In this paper, we present novel modelling technique better capture the electromagnetic behaviour KITWPA without translation symmetry assumption, allowing us to flexibly explore use more complex transmission line structures and predict their performance. Methods: order design optimal performance, investigate different thin film materials, compare pros cons in forming high-gain low-loss medium feasible amplification. We establish if thickness be controlled precisely, material used has less impact on device, as long it topologically defect-free operating within its regime. With insight, propose Titanium Nitride (TiN) our critical temperature easily altered suit applications. further topological effect commonly TiN film, including various non-conducting materials required form amplifier. Results: Both these comprehensive studies led two configurations KITWPA: 1) A 100 nm thick coplanar waveguide amplifier, 2) compact 50 inverted microstrip amplifier. utilise described first part paper operational setup broadest bandwidth both KITWPAs, loss. Conclusions: Finally, conclude actual layout predicted gain-bandwidth product KITWPAs.

متن کاملSuperconducting Microstrip-Fed Antenna Coupled to a Microwave Kinetic Inductance Detector
A proper antenna to couple to a microstrip Microwave Kinetic Inductance Detector (MKID) is designed and simulated. A twin-slot microstrip-fed inline antenna is designed for frequency band of 600-720~GHz integrated with an elliptical lens and coupled to the MKID. A systematic design procedure for design of such antenna with microstrip inline feeding is presented. Whole structure of lens and twin...
متن کاملKinetic inductance and penetration depth of thin superconducting films measured by THz-pulse spectroscopy.
We measure the transmission of THz pulses through thin films of YBa2Cu3O7−δ at temperatures between 10 K and 300 K. The pulses possess a usable bandwidth extending from ∼0.1 – 1.5 THz (3.3 cm – 50 cm). Below Tc we observe pulse reshaping caused by the kinetic inductance of the superconducting charge carriers. From transmission data, we extract values of the London penetration depth, as a functi...
