Embodiment Construction
[0032] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0033] The present invention provides an X / K band composite metamaterial 100, such as figure 1 As shown, it includes a dielectric substrate 103 made of non-conductive material, a metal foil layer attached to the lower surface of the dielectric substrate and a resistive film layer attached to the upper surface of the dielectric substrate, and the dielectric substrate, metal foil layer and resistive film layer Virtually divided into a plurality of periodically arranged unit structures 102; a square metal foil 104 is etched on the metal foil layer of the unit structure 102; a square ring is sputtered on the resistive film layer of the unit structure Shaped resistive film 106; two slits 105 of the same size and perpendicular to each other are hollowed out on the square metal foil 104.
[0034] Among them, on the upper and lower surfaces of the dielectric s...
