| Abstract: | Based on some optics principles, the surface reflection of testing the dielectric constant of dielectric planks by using unrestrained wave is thoroughly analyzed. The analysis shows that the surface reflection affects testing results according to different dielectric materials and different testing methods. The analysis result is testified experimentally with the testing results of some low-comumed dielectric materials. Some factors which can affect the testing accuracy and repeatability are discussed at the end of this paper. |
