Abstract

The electromagnetic response of a high temperature superconducting (HTS) slotline placed in a static magnetic field at varying oblique angles is analyzed using propagation parameters computed by spectral domain method (SDM). The modified two-fluid theory formulated by Coffey and Clem (CC) for the angular dependence is employed to self-consistently determine the vortex dynamical response of the HTS films made of different material purities. The impedance matrix of the slotline obtained using SDM is modified by incorporating the HTS contribution and Galerkin technique is used for the calculation of the propagation parameters. The paper presents the angular dependence of the obliquely angled static magnetic field on signal propagation and explains the results using vortex dynamic effects.

倾斜外加静磁场作用下超导槽线的谱域模拟

利用谱域法（SDM）计算的传播参数，分析了高温超导槽线在不同斜角静磁场中的电磁响应。采用Coffey和Clem （CC）关于角依赖性的修正双流体理论，自洽地确定了不同材料纯度的高温超导薄膜的涡动力响应。将SDM法得到的槽线阻抗矩阵进行修正，加入HTS贡献，并利用伽辽金技术计算传播参数。本文介绍了斜角度静磁场对信号传播的角度依赖性，并利用涡旋动力学效应解释了结果。

期刊介绍： Physica C (Superconductivity and its Applications) publishes peer-reviewed papers on novel developments in the field of superconductivity. Topics include discovery of new superconducting materials and elucidation of their mechanisms, physics of vortex matter, enhancement of critical properties of superconductors, identification of novel properties and processing methods that improve their performance and promote new routes to applications of superconductivity. The main goal of the journal is to publish: 1. Papers that substantially increase the understanding of the fundamental aspects and mechanisms of superconductivity and vortex matter through theoretical and experimental methods. 2. Papers that report on novel physical properties and processing of materials that substantially enhance their critical performance. 3. Papers that promote new or improved routes to applications of superconductivity and/or superconducting materials, and proof-of-concept novel proto-type superconducting devices. The editors of the journal will select papers that are well written and based on thorough research that provide truly novel insights.
