N2 - Multilayer dielectric structure was widely used in radome design, electromagnetic target stealth and microwave/infrared beam combiner. In this paper, the microwave transmittance and transmittance bandwidth in multilayer dielectric structures was studied based on particle swarm optimization. The effect of different numbers of dielectric layers on transmittance bandwidth was analyzed. The results showed that the three-layer dielectric structure can significantly increase the transmittance bandwidth. By researching the effect of dielectric constant on the transmittance bandwidth, it was concluded that when the dielectric constant of the intermediate layer was about 2.2 ~ 3.3 times that of the outer layers or intermediate layer was air in three-layer dielectric structure, high microwave transmittance and wide transmittance bandwidth can be obtained. Based on above conclusion, a beam combiner composed of three dielectric layers was designed, and the thickness of each layer was optimized by particle swarm optimization algorithm. The average transmittance of designed beam combiner was more than 96.5% from 10GHz to 16.4 GHz over the incident angle range of 0° ~ 20°.
