Design of an absorber with high impedance surfaces

High impedance surface comprising lossy frequency surface are employed to design a electromagnetic absorbers. Using transmission line model to analysis the absorbers loaded high impedance surfaces, and find the key parameter of the structure are the FSS shape and surface impedance, substrate parameters. Lastly, we have showed two electromagnetic absorbers loaded high impedance surfaces, and compared with the classical electromagnetic absorbers. Numerical results that demonstrate the validity and efficiency of proposed scheme are presented in this paper.
