Tunnelling of topological line defects in strongly coupled superfluids [PDF]
, 1999 The geometric theory of vortex tunnelling in superfluid liquids is developed. Geometry rules the tunnelling process in the approximation of an incompressible superfluid, which yields the identity of phase and configuration space in the vortex collective ...

Strong Coupling beyond the Light-Line [PDF]
ACS Photonics, 2020 Strong coupling of molecules placed in an optical microcavity may lead to the formation of hybrid states called polaritons; states that inherit characteristics of both the optical cavity modes and the molecular resonance. Developing a better understanding of the matter characteristics of these hybrid states has been the focus of much recent attention ...

IEEE Access, 2021 Based on bionics, we design and analyze the left-handed (LH) characteristics of meta-elements with leaf-shaped structure. The double negative (DNG) frequency band of the initial leaf-shaped LH structure is 5.77-6.17 GHz with a fractional bandwidth of 6.7&

Enhanced Bandwidth and Diversity in Real-Time Analog Signal Processing (R-ASP) using Nonuniform C-section Phasers [PDF]
, 2016 We show that a continuously nonuniform coupled line C-section phaser, as the limiting case of the step discontinuous coupled-line multisection commensurate and non-commensurate phasers, provides enhanced bandwidth and diversity in real-time analog signal

Low-Noise Voltage Controlled Oscillator with Coupled Microstrip Lines of Different Lengths
Известия высших учебных заведений России: Радиоэлектроника, 2020 Introduction. Coupled two- or three-wire microstrip lines are often used to reduce a phase noise of voltage-controlled oscillators (VCOs). Unfortunately, the phase noise was not optimized depending on the lengths of a three-wire coupled microstrip lines ...

Compact 3‐dB directional coupler design based on substrate integrated dual‐strip coaxial line
IET Microwaves, Antennas & Propagation, 2022 A novel compact 3‐dB directional coupler design based on the substrate integrated dual‐strip coaxial line (SIDSCL) is presented. The SIDSCL differs from the conventional substrate integrated coaxial line (SICL) in that the former possesses two central ...

SAMBA: Superconducting antenna-coupled, multi-frequency, bolometric array [PDF]
, 2002 We present a design for a multipixel, multiband (100 GHz, 200 GHz and 400 GHz) submillimeter instrument: SAMBA (Superconducting Antenna-coupled, Multi-frequency, Bolometric Array). SAMBA uses slot antenna coupled bolometers and microstrip filters.
