研究成果

To sum up, benefited from ultrathin corrugated MIM ring resonator, for the first time, we proposed a dual-detection microfluidic chemical sensor based on quarter-mode spoof LSP resonator. By positioning two asymmetric microfluidic channels in the strongest E-field regions, non-uniform perturbation of E-field is obtained. A prototype of our RF chemical sensor is fabricated and measured and the experimental results show a great agreement with our simulation predictions. Our non-contact and non-invasive chemical sensor shows the highest sensitivity among all the dual/multichannel RF sensors; moreover, the size is reduced. Maximum frequency shift occurred, when two microfluidic channels loaded with [DI water, DI water] compared with empty channels. In our structure, this amount (?????????) is reached to 1070 MHz. Formerly, the highest frequency shift recorded was ????????? = 660 MHz for dual/multichannel microwave sensors which belongs to the proposed structure presented in [14]. Furthermore, the RF chemical sensor presented in this paper, shows 87% improvement in sensitivity compared to the best effort [14]. We believe that our proposed dual-channel RF sensor can be advantageously used for promising applications in chemical sensing technology.
