Development and analysis of 3D frequency selective surfaces

The development and transmission/reflection characteristics of a 3D Cylindrical Frequency Selective Surface (FSS) is discussed in this paper. A simulation based investigation shows that the length of the cylinder has significant effect on the frequency characteristics of the FSS. The results indicate that by increasing the length of the cylinder the characteristic behavior of the FSS changes from a band-stop to a band-pass filter response. The effect of introducing different materials into the 3D cylindrical FSS is also examined.
