Effect of Sample Size on Measurement Reliability of Microwave Dielectric Properties of Low-Loss Materials by a Resonant Cavity Method

摘要

The microwave dielectric properties of SrTiO₃ and CaNdAlO₄ single crystals were measured by the resonant cavity method, and the effect of sample size on measurement reliability was investigated. High measurement accuracy could always be achieved for SrTiO₃, while the measurement was completely unreliable for CaNdAlO₄ with small sizes. The difference was attributed to the much higher dielectric constant and electric energy filling factor of SrTiO₃. It is indicated that the sample with much smaller size than usual might also be used for the resonant cavity method, as long as the electric energy filling factor of the sample was high enough.View full textDownload full textRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; var addthis_config = {"data_track_addressbar":true,"ui_click":true}; Add to shortlist Link Permalink http://dx.doi.org/10.1080/00150193.2012.731991
