Embodiment Construction
[0034] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0035] like figure 1 As shown, the non-uniform surface is mainly composed of square sub-wavelength resonant units whose unit size is less than 1 / 4 of the working wavelength, which can be regarded as a uniform medium. Each sub-wavelength resonant unit is mainly composed of the first metal copper sheet 1, The first dielectric layer 2 and the second metal copper sheet 3 are composed of the first metal copper sheet 1 and the second metal copper sheet 3 in the shape of square sheets, the first metal copper sheet 1 and the second metal copper sheet 3 have the same thickness, and the first metal copper sheet 1 and the second metal copper sheet 3 have the same thickness. The side length of the metal copper sheet 1 is less than the side length of the second metal copper sheet 3, the first dielectric layer 2 is a square block, the thickness of the first dielectri...
