Negative refractive index metamaterial with spinel structure and preparation method thereof
The invention discloses a negative refractive index metamaterial with a spinel structure, the general formula of the negative refractive index metamaterial with the spinel structure is xCdCr2X4. (1-x) CuCr2X4, in the formula, x is more than or equal to 0.1 and less than or equal to 0.4, and X is any one of S, Se and Te. The method comprises the following steps: (1) synthesizing powder by a solid phase method; and (2) carrying out tabletting and sintering treatment on the synthesized powder. The metamaterial prepared by the invention has a negative refractive index in a radio frequency band, and the preparation process is simple.
本发明公开一种具有尖晶石结构的负折射率超材料，该尖晶石结构的负折射率超材料的通式为：xCdCr2X4·(1‑x)CuCr2X4，式中0.1≤x≤0.4，X为S、Se和Te中的任意一种。本发明包含以下步骤：（1）固相法合成粉末；（2）对合成粉末进行压片和烧结处理。本发明制备的超材料在射频波段具有负的折射率，并且制备工艺简单。
