In order to obtain good aerodynamic and stealth performance at the same time， based on the principle of combining shape stealth technology with material stealth technology， a design scheme of wing skin based on wave transmission is proposed. In order to balance the relationship between the lift force and the electromagnetic stealth performance of the wave transmitting wing， a surrogate model based strategy is adopted to optimize the geometric parameters of the wave transmitting wing. The results show that after optimization， the transonic wing can maintain good RCS （radar cross section） reduction characteristics in frequency domain and spatial domain and have enough lift conditions. The proposed proxy model has high accuracy， and can be used as an effective means to balance interdisciplinary problems in engineering.
