It is 0.3mm.In second stage, with the differentiation of the topology of metal micro structure, the folding of corresponding metamaterial unit
Penetrate rate and continuously increase (CF of respective antenna one), when frequency is 12.5GHZ, the corresponding refractive index of metamaterial unit is most
Big value nmaxIt is 5.6.
The variations in refractive index scope (1.91-5.6) for obtaining metamaterial unit by above-mentioned differentiation meets design needs.If
The variations in refractive index scope that above-mentioned differentiation obtains metamaterial unit is unsatisfactory for designing needs, and such as maximum is too small, then change WL
With W, emulate again, the variations in refractive index scope until obtaining our needs.
