高温超导滤波器应用的探索与实践

The applications of HTS filters:exploration and practice

自1911年发现超导电性以来,在不断发现新材料,揭示新机理,发展新理论的同时,超导应用也取得了引人瞩目的进展,其中利用超导材料微波损耗很低的特性研制的微波滤波器和微波接收机前端子系统得到了世界各国的重视,并在实际应用中取得了重要成果.本研究组长期从事该领域的研究,并已取得一些成果.该文将从超导滤波器的创新设计方法入手,结合研究组近些年开展的工作,介绍高温超导滤波器及其子系统在无线通讯、气象雷达、射电天文以及空间技术等领域中的应用.

Since the discovery of superconductivity in 1911, new materials have been discovered, new mechanisms revealed, and new theories developed. At the same time, remarkable achievements have been made in the applications of superconductor. Among all the applications, microwave filters and microwave receiver frontend sub-systems, which benefit from the small surface resistance of the superconductor materials, have attracted intensive interests all over the world, and great progress has been made in their applications. Our group has been devoting to the related research and made great results in this area for a long time. In this review, we will introduce a new design method for high temperature superconductor （HTS） filters, and discuss the applications of HTS filters and sub-systems in mobile communications, meteorological radars, radio astronomy, satellite application and other areas, along with the researches performed by our group in recent years.
