Designing a radome with frequency selective surface by using the physical optics method

In this work, a hemispheric radome with conformal frequency selective surface is designed and analyzed by using the physical optics method. The conformal frequency selective surface consists of two layers of substrate and three layers of periodic patches and grids. The radome is manufactured and measured. The comparison between the analysis result of the physical optics method and the experimental result show that they are agree very well, which verify that the physical optics method is an effective method for calculating the electrical large structures.
