摘要: 采用喇叭天线与透镜相结合的准光技术方案，设计了毫米波生物效应聚焦装置,其频率达到95 GHz，辐射功率达GW级。毫米波辐射源传输到波纹喇叭天线产生的波束经透镜变换得到所需的高斯波束，实现波束能量的汇聚。在毫米波辐射源功率为W级的条件下，该装置的焦斑功率密度达到0.01～2 W·cm-2，焦斑面积为0.8～30 cm2。该实验装置在毫米波生物效应实验中已得到成功应用。Abstract: A focusing system, consisting of horn antenna and lens, has been designed for the laboratory experiment of millimeter wave induced bioeffects. It adopts quasi-optical techniques, and can operate at 95 GHz and radiate GW-level power. For the millimeter wave source at W-level, the power density and area of its focal spot are 0.01～2 W·cm-2 and 0.8～30 cm2, respectively. In addition, the system has been applied successfully to the laboratory experiment of millimeter wave induced bioeffects.
