摘　　要：简要介绍了微波点火技术,对四分之一波长同轴谐振腔点火器的发展进行了概述。采用三维电磁仿真软件HFSS模拟了内导体对称环结构的耦合方式。在输入功率为400W时,内导体的顶部电场强度可达到2.3×107 V/m左右,满足汽车发动机在高达1×106 Pa气压下激发等离子体火焰的门限条件—2.25×107 V/m。This article briefly describes the microwave ignition technology, provides an overview on the development of ignition the quarter-wavelength coaxial resonator cavity. 3D electromagnetic simulation software HFSS is used to simulate the inner conductor coupling symmetric ring structure. When the input power is 400 W, the electric field intensity on the top of the inner conductor can reach 2.3 × 10^7 V/m which meet the standard atmospheric pressure up to 10 meet Car Engine excited plasma flame threshold condition 2.25 × 10^7 V/re.
