| Abstract: | The effect of heat treatment process and particle size on microwave electromagnetic properties of Fe73.5Cu1Nb3Si13.5B9 was studied.The absorbing properties of such materials were also tested.The results show that the heat treatment for crystallization conditions will help improve the microwave electromagnetic properties of materials.The microwave electromagnetic properties and the electromagnetic matching parameters increase with the material particle size decreasing.The minimum reflectivity of materials reaches-12 dB,while the frequency width lower than-5 dB reaches 12.5 GHz for Ⅴ class powder. |
