等离子体处理ABS管提升了ABS/Ag镀层太赫兹空芯波导的性能.胶带法测试结果表明,等离子体处理后,银镀层的附着力由5级提升至2级.等离子体处理后的ABS管内表面银层的均匀性和致密度更高,高质量的银层有利于降低波导的损耗.未经等离子体处理的4.2 mm内径的ABS/Ag镀层空芯波导在0.3 THz和0.1 THz时的直线损耗分别为0.72 dB/m和1.47 dB/m,等离子体处理后其损耗分别降至0.70 dB/m和1.44 dB/m,且波导能够在冷热环境中稳定传输太赫兹波.等离子体处理后的样品在超过200小时的湿热老化和16次的高低温循环老化试验后直线损耗升高小于0.1 dB/m,而未经等离子体处理的样品的损耗升高大于1 dB/m.研究结果表明,等离子体处理后的ABS/Ag镀层太赫兹空芯波导损耗更低、传输可靠性更高、耐老化性更好,可用于构建下一代通信、传感及太赫兹成像系统等.
Preparation of flexible low-loss ABS/Ag-coated terahertz hollow waveguide by plasma treatment and study on its transmission reliability
The performance of ABS/Ag-coated terahertz hollow waveguide(HWG)was improved through plasma treatment of the ABS structural tube.The adhesion of the silver(Ag)film to the ABS tube was enhanced from level 5 to level 2 after plasma treatment.The 4.2 mm bore waveguide sample treated with plasma has a more uniform and denser silver film than the untreated sample,which contributes to the reduction of transmission losses from 0.72 dB/m to 0.70 dB/m at 0.3 THz and 1.47 dB/m to 1.44 dB/m at 0.1 THz,respectively.After 200 hours of hydrothermal ag-ing and 16 cycles of high and low temperature cycling testing,the straight loss of the HWG sample treated with plasma increased by less than 0.1 dB/m,while the untreated sample underwent an increase of more than 1.0 dB/m.The results indicate that the ABS/Ag-coated HWG fabricated by plasma treatment has lower loss,higher reliability and better anti-aging performance compared with the untreated sample.It can be potentially used for establishment of next-generation communication,sensing,and THz imaging systems.
