Abstract: A symmetric double-layer frequency selective surface is studied by adopting the symmetric and anti-symmetric excitation method. Transmission properties of the structure are discussed for different dielectric parameters of the structure. It is shown that the frequency response of the structure can be great by improved by choosing suitable dielectric parameters of the covering and coating layers. -
