摘要：

Based on Maxwell's equations' form-invariance to coordinate transformations, an electromagnetic cloaking structure at 10. 14 GHz was designed by cylindrical coordinate transformation and made with metamaterial composed of split-ring resonators. A quick novel experiment method was used to measure the power level of the received microwave signal. The cloaking structure reduced scattering from the hidden object and meanwhile reduced its shadow effect, which was consistent with theoretical expectations. The experiment system reduced the complexity and shortened the time of measurement, which provided a new simple and effective experimental method in this field.
