【Abstract】 In present work,the PTFE based composite dielectric materials with fine ceramic powder have been prepared by using the technology similar to the powder metallurgy.The microstructures of samples have been observed by SEM and analysed by IR. The dielectric properties of samples in microwave have been measured by using disturbing method based on the theories of micro disturbance.更多还原
