Embodiment Construction
[0021] The technical solutions of the present invention will be described in detail below in conjunction with the drawings and embodiments, but the protection scope of the present invention is not limited to the embodiments.
[0022] figure 1 In the embodiment of the present invention, it is a transmission and reflection integrated dual-polarization independent control unit, which loads a broadband / ultra-broadband reflection unit on the basis of a broadband / ultra-broadband polarization rotation transmission unit, and realizes it by optimizing its arrangement Reduction of RCS. In this example t 1 , t 2 , t 3 The thicknesses are 0.5mm, 2.5mm and 3mm respectively, and the cell size is 9.6mm×9.6mm; the parameter x in 101-1 1 =0.2L 1 ,y 1 =0.1L 1 ,z 1 =0.05L 1 ,w 1 =w 2 =0.3, g 1 =0.6, g i1 =0.2,L v1 =b 1* [L 1 -2 * (w 1 +w i1 +g 1 +g i1 )]; 101-3 parameter R 1 =3.3,R 2 =4.7,w 1 =1.4, L=9.6; the width and gap of the first and second metal polarization grids ...
