This study focuses on electromagnetic and thermo- mechanical optimal design for high-temperature broadband radome wall with symmetrical graded porous structure. The position- dependent porosity increases from the two surfaces of the structure to its intermediate layer. Electromagnetic and thermo-mechanical properties of the proposed structure are investigated simultaneously via numerical simulations. Optimal results suggest that the symmetrical porous structure possesses better broadband transmission performance in the 1{100GHz frequency range, in contrast to a traditional A-sandwich structure. The thermo-mechanical investigation also indicates that the novel structure meets the requirement for high- temperature (up to 1400 - C) applications.
