| contents | In this paper, a Frequency Selective Surface fractalized unit cell design previously explored in the literature is replicated then extended and optimized for multilayer FSS morphologies. A 10 mm x 10 mm planar unit cell is used and then iterated on to create a multilayer structure optimized for use as a bandstop filter in the X-band and Ku-band. Substrate thickness, unit cell shift, and number of layers are varied and numerical results are obtained via the finite element method employed by Ansys solver for electromagnetic structures (HFSS). S-parameters for reflection and transmission are obtained at various stages of design optimization to verify the desired bandstop results, and bandpass characteristics are explored at each stage of the design as well. |
