Abstract
In this paper, a novel design structure of a dual-band filter is proposed. The core of the structure is to form a dual-band filter by connecting two sub-filters through a matching network. The matching network can not only improve the flexibility of the design, but also minimize the influence between the two sub-filters. Two sub-filters are designed separately, one of which is composed of interdigital resonators and the other is composed of hairpin resonators. The center frequency and bandwidth of the two passbands are flexible and controllable. Finally, a dual-band high-temperature superconducting (HTS) filter is designed and successfully fabricated on a DyBa2Cu3O7 (DyBCO) thin film on thickness of 0.5 mm LaAlO3 wafer, and the measured results are in good agreement with the simulation results.
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.
