Abstract

Abstract : Highly intense narrowband dielectric and magnetic resonance at microwave frequency. Abstract : A material with a highly intense narrowband microwave resonance (NMR) has significant potential in a broad range of applications, especially in microwave electronics, elementary particle accelerators, and antenna systems. However, the design of NMR materials with intensely intrinsic narrowband resonances is still a great challenge. In this paper, we report a strategy to design NMR materials by the rational construction of one-dimensional core–shell nanowires, utilizing a solution growth process for zeolitic imidazolate frameworks (ZIFs) shell on Ag nanowires and a temperature-controlled pyrolysis process. The pyrolyzed core–shell nanowires show remarkable NMR properties. More importantly, both the NMR intensity and frequency can be tuned by heat-treatment or element doping, expanding the rational design of NMR materials.
