Research On The Millimeter Wave Band-Pass Frequency Selective Surface

In this paper ,we discuss the frequency selective surface(FSS) using for the 8 millimeter wave band-pass and the 2-18GHz band-stop system.First of all, we introduce the conception and working mechanics of FSS. And we discuss the factors which could affect the property of FSS, such as element type and scale, dielectric loading, and so on.Second, we adopt the Floquet theorem to explain and descript the flat surface period structure including FSS , and then provide the common design way of FSS, and then design a type of FSS that correspond to our destination.At last we make out the FSS by proper technique. We measure the transmittance and the reflectance of the sample respectively. We also discuss the result and the problem existing in our manufacture technique then make out the resolutions.
