Fabrication and properties of meta-materials based on multilayer ceramic structure

In recent years, meta-materials received wide attention for its negative refractive index in microwave system. Many papers have reported the theoretical and experience development of meta-materials. The main work of this paper includes fabrication of the samples and measuring the property. We design the parameters of the structure and then using tape-casting technique to fabricate periodic silver structure in the ceramic substrate. The measurement fixture is designed, and HP8720ES vector network analyzer is used to measure the spectra and the field distribution of samples. At about 12 GHz, samples had an obvious photonic band gap from S ₂₁ parameter measure results. By the field distribution in the two dimension plane of samples, we obtained the abnormal refraction phenomenon which can audio-visual validate the existence of meta-materials.
