ScholarBank@NUS Repository. https://doi.org/10.1063/1.3638448 | Abstract: | Microwave attenuation characteristics and magnetic and dielectric properties have been studied for Ba3CoxZn 2-xFe24O41 with x = 0.8 and 2.0 ferrite flaky-filler composites. Results show that μ0′ and max ″ are enhanced by > 150 and > 70, respectively, and ′ and ″ are almost the same, as compared to conventional composites. Therefore, the percentage bandwidth WP is expanded from 110 to 150 for reflectivity RL ≤-10 dB for the flaky-filler composites, which achieves 75 of the theoretically maximum bandwidth. For all composites, two matching frequencies are found. The first matching frequency is attributed to the quarter-wavelength resonator and the second matching frequency is mainly determined by the values of both μ′ and ε′. At the second matching thickness, the flaky-filler composites also exhibit good attenuation characteristics with low reflectivity of RL | Source Title: | Journal of Applied Physics | URI: | http://scholarbank.nus.edu.sg/handle/10635/116325 | ISSN: | 00218979 | DOI: | 10.1063/1.3638448 |
