介绍了一种集成驱动的微流体可重构慢波移相器。MRPS是基于一个选择性金属化板（SMP）可重新定位在微流体通道放置在靠近微带线。SMP重新定位产生可变电容负载以改变传播波的速度。该设备显示$|第21章|$ , $|S_{十一}|$，相位性能的特点是相对于重力的变化分别不超过0.16 dB，3.02 dB和7.73°稳定。振动测试显示IL为0.08 dB，回波损耗（RL）为1.72 dB，相位变化为4.23°。该器械预期可处理5.2 W的连续射频功率。
A microfluidically reconfigurable slow wave phase shifter (MRPS) with integrated actuation is introduced. MRPS is based on a selectively metalized plate (SMP) repositionable within a microfluidic channel placed in close proximity to a microstrip line. SMP repositioning creates a variable capacitive loading to alter the speed of the propagating wave. The device exhibits $|S_{21}|$ , $|S_{11}|$ , and phase performances are characterized to be stable with respect to gravity by no more than 0.16 dB, 3.02 dB, and 7.73° variations, respectively. Vibration test shows 0.08 dB in IL, 1.72 dB in return loss (RL), and 4.23° in phase variations. The device is expected to handle 5.2 W of continuous RF power.
